+Other conversions that have also been done are SDL_Mixer.h, SDL_Net.h, SDL_Image.h, SDL_ttf, SMPEG.h, SDL_sound and the SFont library,
+which are all included in this distribution.
+
+It allows you to access all the functions within the SDL libraries under Windows, Linux and FreeBSD, so you can write cross-platform games or multimedia applications.
+
+Installation Instructions
+-------------------------
+Windows - We now have a semi-automated setup under Windows ( thanks to David House and the Jedi JCL team ).
+ Once you have extracted the zip file, simply double click on the "JEDISDLWin32Installer.exe" to have the correct paths added to your respective
+ IDEs. All IDEs from Delphi 4 - 7 are supported and it also adds a link to the .CHM help file under the Tools menu.
+
+Linux - Alternatively if you use Linux or want to to manually install the paths, then make sure you read the "Getting Started.html" file ( ideal for those who are new to JEDI-SDL ) and is now included as a guide to help getting everything setup for smooth compilation.
+
+Also included is a guide of how to use Sourceforge using TortoiseCVS under Windows ( Linux guide is under development ).
+Both documents can be found in the "documentation" directory.
+

+
+
+Beta 4 : The JEDI-SDL home page is now located @ http://www.delphi-jedi.org/Jedi:TEAM_SDL_HOME
+ All Demos ( including OpenGL Demos ) now compile under both Kylix and Delphi.
+ I have added quite a few more OpenGL examples, we are now up to Nehe tutorial 12.
+ All OpenGL demos also show how to handle Window resizing.
+ Included an OpenGL demo called Puntos by Gustavo Maximo.
+ Ported Jan Horn's OpenGL MetaBalls and also SkyBox demo to SDL.
+ Ported Ilkka Tuomioja's OpenGL Quake 2 Model Viewer/Animator to SDL.
+ NOTE : All OpenGL demos require OpenGL12.pas which can be found at...
+ http://www.lischke-online.de/Graphics.html#OpenGL12
+ I also fixed a conversion bug to do with SDL_MustLock and also a conversion omission to do with various events.
+ Fixed a conversion bug with SDL_CDOpen ( as suggested on the mailing list ).
+ Added the GetPixel and PuxPixel functions to the SDLUtils.pas file.
+ Jason Farmer has donated SFont, a simple, yet effective Font library he converted for JEDI-SDL.
+ It contains 4 Demos show how to best use it.
+ Added TUInt8Array and PUIntArray to SDL.pas after suggestions from Matthias Thoma and Eric Grange.
+ In the file area of the JEDI-SDL mailing list ( http://groups.yahoo.com/group/JEDI-SDL/files/DTTSrc/ there
+ is a fully functional 3D network game called DeathTruckTion v1.0 written by the TNTeam that makes use of
+ JEDI-SDL and is just too big to include with this distribution but is well worth looking at as it works under Windows and Linux!
+ Gustavo Maxima is working on translating the JEDI-SDL Documentation to Spanish and Portugese.
+ The Mouse Demo has now been speeded up considerably and it is very responsive now.
+ Dean Ellis will provide steps on how to compile the demos using the Free Pascal compiler.
+ Jason Farmer and I are working on a series of Tutorials that should hopefully be out soon.
+ David Aclan has donated a SMpeg component that should work under Kylix.
+ Róbert Kisnémeth, has been hard at work, and has donated some new demos he has created with a SpriteEngine ( which he also donated ).
+ He has also donated a couple of games called BlitzBomber and Oxygene ( which uses the SpriteEngine ) and added a couple of useful
+ functions to SDLUtils.pas.
+ The Functions added are SDL_FlipV, SDL_FlipH, SDL_NewPutPixel ( assembler version ), SDL_AddPixel, SDL_SubPixel, SDL_DrawLine, SDL_AddLine,
+ SDL_SubLine, SDL_AddSurface, SDL_SubSurface, SDL_MonoSurface & SDL_TexturedSurface.
+ He has also donated a Font Blitting class and demo called SDL_MonoFonts which supports alignment like Left, Right and Center.
+ He and Thomas are also working on a GUI library.
+ Jason Farmer has donated a set of Image Filtering functions which add quite a few interesting effects. Check the SDL_Filter sub-directory for more
+ info.
+ Christian Hackbart also donated an OpenGL BlockOut clone.
+
+
+Beta 3 : I have added conversions for SDL_env.h, SDL_Mixer.h and SDL_Net.h while Matthias Thoma has added conversions for SDL_Image.h and SMPEG.h.
+ This version is also SDL version 1.2.0 compliant.
+ This release also adds demos for the SDL_Image, SDL_Mixer and SDL_Net libraries.
+ There are now also some OpenGL demos that make some use of SDL as well as a demo on how to use the Mouse with Clickable regions.
+ A conversion bug, that was pointed out by Clem Vasseur, has also been fixed.
+ There is now a mailing list that has been set up at http://groups.yahoo.com/group/JEDI-SDL/join/ so we can all learn from each other how to use
+ these libraries.
+ Demos have not been unified into single .dpr files for each demo, thus showing how you would write a crossplatform game using only 1 .dpr file.
+ There is also a documentation directory that is currently in HTML format. All code examples in the documentation have been converted to Object
+ Pascal but are untested.
+ I Also fixed a few conversion bugs which I came across while converting the documentation.
+
+Beta 2 : I have added conversions for SDL_active.h, SDL_thread.h, SDL_mutex.h and
+ SDL_error.h, Matthias Thoma has added Linux Support and JEDI compliancy so these
+ units and examples are now x-platform and x-compiler compilable.
+ I also added Tom Jones' SDLUtils.pas file;
+ Matthias also cleaned up the 2 new demos and made them work on both Linux and
+ Windows.
+
+Beta 1 : Initial Release;
+
+
+There are now 5 examples included with this JEDI-SDL distribution.
+1. Is the TestWin application, which is based on the testwin application that comes with the SDL SDK, only my version has a gui front end to the options available and has been compiled under Delphi 4.03. It should be compatible with Delphi 3.0 onwards ( though Delphi 2 compatibility has not been tested ).
+
+2. A Plasma example which was converted from one found on the Demos page of the SDL site.
+
+3. A Voxel terrain following demo, which was converted from one found on the Demos page of the SDL site. This one should be of interest to others as it shows how to handle keyboard events when using SDL.
+
+4. A Mouse handling demo that shows how to use transparency and clickable regions.
+
+5. A Space Invaders style game called Aliens which shows the use of SDL, SDL_Image and SDL_Mixer. This game shows how to handle sound, keyboards and some basic collision detection. It is a conversion of one found on the SDL Demos page.
+
+There are also 14 OpenGL demos that are based on the NeHe tutorials <nehe.gamedev.net>. The other 3 OpenGL demos are Jan Horns' OpenGL demo, A Quake 2 Model viewer that I ported and a Demo by Gustavo Maxima called Puntos.
+
+If writing your own, just make sure that the SDL.pas file is in your projects path for compiling and that the SDL.dll file is in your path when running the compiled app.
+
+Please test these units and report problems to the JEDI-SDL mailing list @ http://groups.yahoo.com/group/JEDI-SDL/ outlining steps under which the error occurred. If you convert any more demos please send them to me so that I can
+include them in the ditribution for others to learn from.
+
+Also if you are using these Units to write any games
+please let me know about it so that I can post the information to the http://www.DelphiGamer.com site.
+
+The plan is to have this unit JEDI certified at some point so that it can be included on the Delphi and Kylix CDs, so all feedback is greatly welcomed.

+// This unit contains many needed types, functions and procedures for
+// quaternion, vector and matrix arithmetics. It is specifically designed
+// for geometric calculations within R3 (affine vector space)
+// and R4 (homogeneous vector space).
+//
+// Note: The terms 'affine' or 'affine coordinates' are not really correct here
+// because an 'affine transformation' describes generally a transformation which leads
+// to a uniquely solvable system of equations and has nothing to do with the dimensionality
+// of a vector. One could use 'projective coordinates' but this is also not really correct
+// and since I haven't found a better name (or even any correct one), 'affine' is as good
+// as any other one.
+//
+// Identifiers containing no dimensionality (like affine or homogeneous)
+// and no datatype (integer..extended) are supposed as R4 representation
+// with 'single' floating point type (examples are TVector, TMatrix,
+// and TQuaternion). The default data type is 'single' ('GLFloat' for OpenGL)
+// and used in all routines (except conversions and trigonometric functions).
+//
+// Routines with an open array as argument can either take Func([1,2,3,4,..]) or Func(Vect).
+// The latter is prefered, since no extra stack operations is required.
+// Note: Be careful while passing open array elements! If you pass more elements
+// than there's room in the result the behaviour will be unpredictable.
+//
+// If not otherwise stated, all angles are given in radians
+// (instead of degrees). Use RadToDeg or DegToRad to convert between them.
+//
+// Geometry.pas was assembled from different sources (like GraphicGems)
+// and relevant books or based on self written code, respectivly.
+//
+// Note: Some aspects need to be considered when using Delphi and pure
+// assembler code. Delphi ensures that the direction flag is always
+// cleared while entering a function and expects it cleared on return.
+// This is in particular important in routines with (CPU) string commands (MOVSD etc.)
+// The registers EDI, ESI and EBX (as well as the stack management
+// registers EBP and ESP) must not be changed! EAX, ECX and EDX are
+// freely available and mostly used for parameter.

+ Y^2 + (1-Y^2) Cos(t) = M[1][1]
+ Z^2 + (1-Z^2) Cos(t) = M[2][2]

+ X^2 + Y^2 + Z^2 - (M[0][0] + M[1][1] + M[2][2]) =
+ - (3 - X^2 - Y^2 - Z^2) Cos(t)
+
+ Since (X^2 + Y^2 + Z^2) = 1, we can rewrite as:
+
+ Cos(t) = (1 - (M[0][0] + M[1][1] + M[2][2])) / 2
+
+ Solving for t, we get:
+
+ t = Acos(((M[0][0] + M[1][1] + M[2][2]) - 1) / 2)
+
+ We can substitute t into the equations for X^2, Y^2, and Z^2 above

+ Revision 1.5 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.4 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.3 2005/05/22 18:52:09 savage
+ Changes as suggested by Michalis Kamburelis. Thanks again.
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:18 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.6 2003/06/02 12:32:12 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+ Revision 1.6 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.5 2006/01/11 22:39:02 drellis
+ Updated to Support Up to OpenGL 2.0
+
+ Revision 1.4 2005/01/05 00:28:40 savage
+ Forgot to wrap a couple of Load_WGL function calls with an IFDEF WIN32. Fixed so now compiles under Linux as well.
+
+ Revision 1.3 2004/08/24 19:33:06 savage
+ Removed declarations of SDL_GL_GetProcAddress as the correct ones are in sdl.pas.
+
+ Revision 1.2 2004/08/09 00:38:01 savage
+ Updated to Tom's latest version. May contains bugs, but I hope not.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.6 2004/03/28 00:28:43 savage
+ Fixed some glSecondaryColor definitions...
+
+ Revision 1.5 2004/02/20 17:18:16 savage
+ Forgot to prefix function pointer with @ for FPC and other Pascal compilers.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.7 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+ Revision 1.8 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.7 2006/11/26 16:35:49 savage
+ Messed up the last change to GLUtessCombineDataProc, had to reapply it. Thanks Michalis.
+
+ Revision 1.6 2006/11/25 23:38:02 savage
+ Changes as proposed by Michalis Kamburelis for better FPC support
+
+ Revision 1.5 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.4 2005/05/22 18:52:09 savage
+ Changes as suggested by Michalis Kamburelis. Thanks again.
+
+ Revision 1.3 2004/10/07 21:01:29 savage
+ Fix for FPC
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.4 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.
+
+ Revision 1.3 2003/05/29 22:55:00 savage
+ Make use of new DLLFunctions
+
+ Revision 1.2 2003/05/27 09:39:53 savage
+ Added better Gnu Pascal support.
+
+ Revision 1.1 2003/05/11 13:18:03 savage
+ Newest OpenGL Headers For Delphi, Kylix and FPC
+
+ Revision 1.2 2002/10/13 14:36:47 sg
+ * Win32 fix: The OS symbol is called "Win32", not "Windows"
+
+ Revision 1.1 2002/10/13 13:57:31 sg
+ * Finally, the new units are available: Match the C headers more closely;
+ support for OpenGL extensions, and much more. Based on the Delphi units
+ by Tom Nuydens of delphi3d.net

+ Revision 1.4 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.3 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.5 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.4 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.4 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+Source, Legals ("Licence")
+--------------------------
+The official site to get this parser is http://www.destructor.de/
+
+Usage and Distribution of this Source Code is ruled by the
+"Destructor.de Source code Licence" (DSL) which comes with this file or
+can be downloaded at http://www.destructor.de/
+
+IN SHORT: Usage and distribution of this source code is free.
+ You use it completely on your own risk.
+
+Postcardware
+------------
+If you like this code, please send a postcard of your city to my above address.
+===============================================================================================
+!!! All parts of this code which are not finished or not conforming exactly to
+ the XmlSpec are marked with three exclamation marks
+
+-!- Parts where the parser may be able to detect errors in the document's syntax are
+ marked with the dash-exlamation mark-dash sequence.
+===============================================================================================
+Terminology:
+------------
+- Start: Start of a buffer part
+- Final: End (last character) of a buffer part
+- DTD: Document Type Definition
+- DTDc: Document Type Declaration
+- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No.
+- Cur*: Fields concerning the "Current" part passed back by the "Scan" method
+===============================================================================================
+Scanning the XML document
+-------------------------
+- Create TXmlParser Instance MyXml := TXmlParser.Create;
+- Load XML Document MyXml.LoadFromFile (Filename);
+- Start Scanning MyXml.StartScan;
+- Scan Loop WHILE MyXml.Scan DO
+- Test for Part Type CASE MyXml.CurPartType OF
+- Handle Parts ... : ;;;
+- Handle Parts ... : ;;;
+- Handle Parts ... : ;;;
+ END;
+- Destroy MyXml.Free;
+===============================================================================================
+Loading the XML document
+------------------------
+You can load the XML document from a file with the "LoadFromFile" method.
+It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your
+application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever
+protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method.
+"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated
+string, thereby creating a copy of that buffer.
+"SetBuffer" just takes the pointer to another buffer, which means that the given
+buffer pointer must be valid while the document is accessed via TXmlParser.
+===============================================================================================
+Encodings:
+----------
+This XML parser kind of "understands" the following encodings:
+- UTF-8
+- ISO-8859-1
+- Windows-1252
+
+Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry.
+
+Every string which has to be passed to the application passes the virtual method
+"TranslateEncoding" which translates the string from the current encoding (stored in
+"CurEncoding") into the encoding the application wishes to receive.
+The "TranslateEncoding" method that is built into TXmlParser assumes that the application
+wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able
+to convert UTF-8 and ISO-8859-1 encodings.
+For other source and target encodings, you will have to override "TranslateEncoding".
+===============================================================================================
+Buffer Handling
+---------------
+- The document must be loaded completely into a piece of RAM
+- All character positions are referenced by PChar pointers
+- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0)
+ or reference the buffer of another instance or object (then, FBuffersize is 0 and
+ FBuffer is not NIL)
+- The Property DocBuffer passes back a pointer to the first byte of the document. If there
+ is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character.
+===============================================================================================
+Whitespace Handling
+-------------------
+The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content:
+While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all
+Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are
+compressed to one.
+If the "Scan" method reports a ptContent part, the application can get the original text
+with all whitespace characters by extracting the characters from "CurStart" to "CurFinal".
+If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or
+use CurStart/CurFinal.
+Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters
+as the XmlSpec requires (XmlSpec 2.11).
+The xml:space attribute is not handled by TXmlParser. This is on behalf of the application.
+===============================================================================================
+Non-XML-Conforming
+------------------
+TXmlParser does not conform 100 % exactly to the XmlSpec:
+- UTF-16 is not supported (XmlSpec 2.2)
+ (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser)
+- As the parser only works with single byte strings, all Unicode characters > 255
+ can currently not be handled correctly.
+- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11)
+ (Workaround: The Application can access the text contents on its own [CurStart, CurFinal],
+ thereby applying every normalization it wishes to)
+- The attribute value normalization does not work exactly as defined in the
+ Second Edition of the XML 1.0 specification.
+- See also the code parts marked with three consecutive exclamation marks. These are
+ parts which are not finished in the current code release.
+
+This list may be incomplete, so it may grow if I get to know any other points.
+As work on the parser proceeds, this list may also shrink.
+===============================================================================================
+Things Todo
+-----------
+- Introduce a new event/callback which is called when there is an unresolvable
+ entity or character reference
+- Support Unicode
+- Use Streams instead of reading the whole XML into memory

+
+Date Author Version Changes
+-----------------------------------------------------------------------------------------------
+2000-03-16 HeySt 1.0.0 Start
+2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site
+2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent
+2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway)
+2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements;
+ Should be backwards compatible.
+ AnalyzeDtdc: Set CurPartType to ptDtdc
+2000-04-23 HeySt 1.0.5 New class TObjectList. Eliminated reference to the Delphi 5
+ "Contnrs" unit so LibXmlParser is Delphi 4 compatible.
+2000-07-03 HeySt 1.0.6 TNvpNode: Added Constructor
+2000-07-11 HeySt 1.0.7 Removed "Windows" from USES clause
+ Added three-exclamation-mark comments for Utf8ToAnsi/AnsiToUtf8
+ Added three-exclamation-mark comments for CHR function calls
+2000-07-23 HeySt 1.0.8 TXmlParser.Clear: CurAttr.Clear; EntityStack.Clear;
+ (This was not a bug; just defensive programming)
+2000-07-29 HeySt 1.0.9 TNvpList: Added methods: Node(Index), Value(Index), Name(Index);
+2000-10-07 HeySt Introduced Conditional Defines
+ Uses Contnrs unit and its TObjectList class again for
+ Delphi 5 and newer versions
+2001-01-30 HeySt Introduced Version Numbering
+ Made LoadFromFile and LoadFromBuffer BOOLEAN functions
+ Introduced FileMode parameter for LoadFromFile
+ BugFix: TAttrList.Analyze: Must add CWhitespace to ExtractName call
+ Comments worked over
+2001-02-28 HeySt 1.0.10 Completely worked over and tested the UTF-8 functions
+ Fixed a bug in TXmlParser.Scan which caused it to start over when it
+ was called after the end of scanning, resulting in an endless loop
+ TEntityStack is now a TObjectList instead of TList
+2001-07-03 HeySt 1.0.11 Updated Compiler Version IFDEFs for Kylix
+2001-07-11 HeySt 1.0.12 New TCustomXmlScanner component (taken over from LibXmlComps.pas)
+2001-07-14 HeySt 1.0.13 Bugfix TCustomXmlScanner.FOnTranslateEncoding
+2001-10-22 HeySt Don't clear CurName anymore when the parser finds a CDATA section.
+2001-12-03 HeySt 1.0.14 TObjectList.Clear: Make call to INHERITED method (fixes a memory leak)
+2001-12-05 HeySt 1.0.15 TObjectList.Clear: removed call to INHERITED method
+ TObjectList.Destroy: Inserted SetCapacity call.
+ Reduces need for frequent re-allocation of pointer buffer
+ Dedicated to my father, Theodor Heymann
+2002-06-26 HeySt 1.0.16 TXmlParser.Scan: Fixed a bug with PIs whose name is beginning
+ with 'xml'. Thanks to Uwe Kamm for submitting this bug.
+ The CurEncoding property is now always in uppercase letters (the XML
+ spec wants it to be treated case independently so when it's uppercase
+ comparisons are faster)
+2002-03-04 HeySt 1.0.17 Included an IFDEF for Delphi 7 (VER150) and Kylix
+ There is a new symbol HAS_CONTNRS_UNIT which is used now to
+ distinguish between IDEs which come with the Contnrs unit and
+ those that don't.

+ Revision 1.4 2004/02/20 17:19:10 savage
+ Added Calling convention to Win32 functions just in case.
+
+ Revision 1.3 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.2 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.1 2004/02/14 00:04:50 savage
+ dllfuncs conflicts with FreePascal so it has been renamed back to the moduleloader.pas

+ SDL_ASYNCBLIT means that SDL will try to perform asynchronous blits with

+ SDL will wait for current blits to finish before returning from the lock.

+ if the hardware supports hardware acceleration of alpha blits between
+ two surfaces in video memory, to place the surface in video memory
+ if possible, otherwise it will be placed in system memory.
+ If the surface is created in video memory, blits will be _much_ faster,
+ but the surface format must be identical to the video surface format,
+ and the only way to access the pixels member of the surface is to use
+ the SDL_LockSurface() and SDL_UnlockSurface() calls.
+ If the requested surface actually resides in video memory, SDL_HWSURFACE
+ will be set in the flags member of the returned surface. If for some

+ Revision 1.2 2004/02/18 22:52:53 savage
+ Forgot to add jedi-sdl.inc file. It's there now.
+
+ Revision 1.1 2004/02/18 22:35:54 savage
+ Brought sdl.pas up to 1.2.7 compatability
+ Thus...
+ Added SDL_GL_STEREO,
+ SDL_GL_MULTISAMPLEBUFFERS,
+ SDL_GL_MULTISAMPLESAMPLES
+
+ Add DLL/Shared object functions
+ function SDL_LoadObject( const sofile : PChar ) : Pointer;
+
+ function SDL_LoadFunction( handle : Pointer; const name : PChar ) : Pointer;
+
+ procedure SDL_UnloadObject( handle : Pointer );
+
+ Added function to create RWops from const memory: SDL_RWFromConstMem()
+ function SDL_RWFromConstMem(const mem: Pointer; size: Integer) : PSDL_RWops;
+
+ Ported SDL_cpuinfo.h so Now you can test for Specific CPU types.

+{
+ $Log: sdlinput.pas,v $
+ Revision 1.9 2007/08/22 21:18:43 savage
+ Thanks to Dean for his MouseDelta patch.
+
+ Revision 1.8 2005/08/03 18:57:32 savage
+ Various updates and additions. Mainly to handle OpenGL 3D Window support and better cursor support for the mouse class
+
+ Revision 1.7 2004/09/30 22:32:04 savage
+ Updated with slightly different header comments
+
+ Revision 1.6 2004/09/12 21:52:58 savage
+ Slight changes to fix some issues with the sdl classes.
+
+ Revision 1.5 2004/05/10 21:11:49 savage
+ changes required to help get SoAoS off the ground.
+
+ Revision 1.4 2004/05/03 22:38:40 savage
+ Added the ability to enable or disable certain inputs @ runtime. Basically it just does not call UpdateInput if Enabled = false.
+ Can also disable and enable input devices via the InputManager.
+
+ Revision 1.3 2004/04/28 21:27:01 savage
+ Updated Joystick code and event handlers. Needs testing...
+
+ Revision 1.2 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.1 2004/02/05 00:08:20 savage
+ Module 1.0 release

+ Revision 1.15 2007/12/05 22:52:23 savage
+ Better Mac OS X support for Frameworks.
+
+ Revision 1.14 2007/05/29 21:31:13 savage
+ Changes as suggested by Almindor for 64bit compatibility.
+
+ Revision 1.13 2007/05/20 20:30:54 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.12 2006/12/02 00:14:40 savage
+ Updated to latest version
+
+ Revision 1.11 2005/04/10 18:22:59 savage
+ Changes as suggested by Michalis, thanks.
+
+ Revision 1.10 2005/04/10 11:48:33 savage
+ Changes as suggested by Michalis, thanks.
+
+ Revision 1.9 2005/01/05 01:47:07 savage
+ Changed LibName to reflect what MacOS X should have. ie libSDL*-1.2.0.dylib respectively.
+
+ Revision 1.8 2005/01/04 23:14:44 savage
+ Changed LibName to reflect what most Linux distros will have. ie libSDL*-1.2.so.0 respectively.
+
+ Revision 1.7 2005/01/01 02:03:12 savage
+ Updated to v1.2.4
+
+ Revision 1.6 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.5 2004/05/10 14:10:04 savage
+ Initial MacOS X support. Fixed defines for MACOS ( Classic ) and DARWIN ( MacOS X ).
+
+ Revision 1.4 2004/04/13 09:32:08 savage
+ Changed Shared object names back to just the .so extension to avoid conflicts on various Linux/Unix distros. Therefore developers will need to create Symbolic links to the actual Share Objects if necessary.
+
+ Revision 1.3 2004/04/01 20:53:23 savage
+ Changed Linux Shared Object names so they reflect the Symbolic Links that are created when installing the RPMs from the SDL site.
+
+ Revision 1.2 2004/03/30 20:23:28 savage
+ Tidied up use of UNIX compiler directive.
+
+ Revision 1.1 2004/02/14 23:35:42 savage
+ version 1 of sdl_image, sdl_mixer and smpeg.

+
+2. You need to install smpeg 0.4.4 - www.lokigames.com if it is not already
+ installed on your system.
+ Once smpeg is installed, navigate to your /usr/lib/ directory via a commandline and

+ with the following command ( assuming you are in /usr/lib/ )...
+ ln -s libsmpeg-0.4.so.0 libsmpeg.so
+
+
+3. Then compile using:
+ dcc video60.dpk - Kylix or D6, video40.dpk - D4, video50 - D5
+ dcc MPEGPlay.dpr
+
+4. Run the app and play some MPEGs.

+{ October 12 2001 - DA : Various changes as suggested by David Acklam }
+{ }
+{ April 03 2003 - DL : Added jedi-sdl.inc include file to support more }
+{ Pascal compilers. Initial support is now included }
+{ for GnuPascal, VirtualPascal, TMT and obviously }
+{ continue support for Delphi Kylix and FreePascal. }
+{ }
+{ April 08 2003 - MK : Aka Mr Kroket - Added Better FPC support }
+{ Fixed all invalid calls to DLL. }
+{ Changed constant names to: }
+{ const }
+{ STATUS_SMPEG_ERROR = -1; }
+{ STATUS_SMPEG_STOPPED = 0; }
+{ STATUS_SMPEG_PLAYING = 1; }
+{ because SMPEG_ERROR is a function (_SMPEG_error }
+{ isn't correct), and cannot be two elements with the }
+{ same name }
+{ }
+{ April 24 2003 - DL : under instruction from Alexey Barkovoy, I have added}
+{ better TMT Pascal support and under instruction }
+{ from Prof. Abimbola Olowofoyeku (The African Chief),}
+{ I have added better Gnu Pascal support }
+{ }
+{ April 30 2003 - DL : under instruction from David Mears AKA }

+ Revision 1.12 2007/12/05 22:54:30 savage
+ Better Mac OS X support for Frameworks.
+
+ Revision 1.11 2007/05/20 20:32:45 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.10 2005/04/10 11:48:33 savage
+ Changes as suggested by Michalis, thanks.
+
+ Revision 1.9 2005/01/05 01:47:15 savage
+ Changed LibName to reflect what MacOS X should have. ie libSDL*-1.2.0.dylib respectively.
+
+ Revision 1.8 2005/01/04 23:14:59 savage
+ Changed LibName to reflect what most Linux distros will have. ie libSDL*-1.2.so.0 respectively.
+
+ Revision 1.7 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.6 2004/05/10 14:10:04 savage
+ Initial MacOS X support. Fixed defines for MACOS ( Classic ) and DARWIN ( MacOS X ).
+
+ Revision 1.5 2004/04/13 09:32:08 savage
+ Changed Shared object names back to just the .so extension to avoid conflicts on various Linux/Unix distros. Therefore developers will need to create Symbolic links to the actual Share Objects if necessary.
+
+ Revision 1.4 2004/04/02 10:40:55 savage
+ Changed Linux Shared Object name so they reflect the Symbolic Links that are created when installing the RPMs from the SDL site.
+
+ Revision 1.3 2004/03/31 22:20:02 savage
+ Windows unit not used in this file, so it was removed to keep the code tidy.
+
+ Revision 1.2 2004/03/30 20:23:28 savage
+ Tidied up use of UNIX compiler directive.
+
+ Revision 1.1 2004/02/14 23:35:42 savage
+ version 1 of sdl_image, sdl_mixer and smpeg.

+{
+ Version 1.4361
+ 2003-03-04 - Fixed important bug for simple transparency when using
+ RGB, Grayscale color modes
+
+ Version 1.436

+ extra data may be acessed using ExtraScanline property
+ * Fixed * a bug on tIMe chunk
+ French translation included (Thanks to IBE Software)
+ Bugs fixed
+
+ Version 1.432
+ 2002-08-24 - * NEW * A new method, CreateAlpha will transform the
+ current image into partial transparency.
+ Help file updated with a new article on how to handle
+ partial transparency.
+
+ Version 1.431

+The following changes were made by Lukas Gebauer (geby@volny.cz). In addition, some changes from a previous D5-compatible version were merged, and the supplied sqlite3.dll is updated to version 3.2.2
+
+Notes from Lukas:
+
+- added support for delphi 4+
+
+- datatype constants matches SQlite datatypes contants. (otherwise in some situations you got bad column datatype!)
+
+- removed dependency on strutils
+
+- code is reformated to better look (official borland formationg
+rules)
+
+- added some pragma's after database is open (temp is in memory)
+
+- TSQLiteDatabase.GetTableValue(const SQL: string): int64 for easy call of SQL commands what returning one number only. (like select
+count(*)...)
+
+- TSQLiteDatabase.GetTableString(const SQL: string): String for easy call of SQL commands what returning one string only. (like PRAGMA
+integrity_check)
+
+- TSQLiteDatabase.SetTimeout(Value: integer); you can set timeout for accessing to some table. Good for database sharing!
+
+- TSQLiteDatabase.version: string; returns SQLITE version string
+
+- removed bool fieldtype (it is not natural SQLite3 type)
+
+- fild type detection by Sqite3_columnType knows REAL too.
+
+- integer filedtype is based on Int64
+
+- GetFields can get data from any supported fieldtype
+
+- changed some integers to cardinal for avoid signed and unsigned mismatch
+
+- TSqliteTable.FieldAsInteger(I: cardinal): int64; returns int64
+
+
+3 May 2005 Fixed bug where strupper called on column type before checking for nil
+
+2 May 2005 Add extra check for nil in TSqliteTable.Destroy, thanks to Tim Maddrell
+
+22 Apr 2005 Revise TSqliteTable.Destroy to fix memory leak with dtStr type (thanks to
+Jose Brito)
+
+21 Apr 2005 Quick revision to fix case sensitivity in detecting column type,
+and remove PRAGMA full_column_names = 1 which is deprecated. Warning: may break code. Fix your SQL code so that all column names in a result set are unique.
+
+21 Feb 2005 Sqlite DLL now 3.1.3
+
+19 Feb 2005 Revised for Sqlite 3.1.2

+What's the point?
+=================
+BASS is an audio library for use in Windows and MacOSX software. Its
+purpose is to provide the most powerful and efficient (yet easy to use),
+sample, stream, MOD music, and recording functions. All in a tiny DLL,
+under 100KB in size.
+
+See the documentation for descriptions of all the BASS functions. You
+should also look at the included example program source-codes for some
+examples of how to use BASS in your own programs.
+
+
+Requirements
+============
+Win32 version
+-------------
+BASS requires DirectX 3 or above for output. BASS does not require that a
+soundcard with DirectSound/DirectSound3D hardware accelerated drivers is
+installed, but it does improve performance if there is one. BASS also takes
+advantage of MMX, which improves the performance of the MOD music playback.
+
+MacOSX version
+--------------
+OSX 10.3 or above is recommended. BASS uses CoreAudio for output, so there
+are no special library/driver requirements. BASS supports both PowerPC and
+Intel Macs.
+
+
+Main Features
+=============
+* Samples
+- supports WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples
+
+* Sample streams
+- stream any sample data in 8/16/32 bit
+
+* File streams
+- MP3/MP2/MP1/OGG/WAV/AIFF file streaming
+
+* Internet file streaming
+- stream MP3/MP2/MP1/OGG/WAV/AIFF files from the internet (inc. Shout/Icecast)
+
+* User file streaming
+- stream MP3/MP2/MP1/OGG/WAV/AIFF files from anywhere using any delivery method
+
+* Multi-channel streaming
+- support for more than plain stereo, including multi-channel OGG/WAV/AIFF files
+
+* MOD music
+- uses the same engine as XMPlay = best accuracy, speed and quality
+
+* MO3 music
+- MP3/OGG compressed MOD music
+
+* Add-on system
+- support for more formats is available via add-ons (aka plugins)
+
+* Multiple outputs
+- simultaneously use multiple soundcards, and move channels between them
+
+* Recording
+- flexible recording system, with support for multiple devices
+
+* Decode without playback
+- streams and musics can be outputted in any way you want
+
+* Speaker assignment
+- assign streams and musics to specific speakers
+
+* High precision synchronization
+- synchronize events in your software to the music
+
+* DirectX 8 effects
+- chorus/compressor/distortion/echo/flanger/gargle/parameq/reverb
+
+* User defined DSP functions
+- custom effects may be applied to musics and streams
+
+* 32 bit floating-point decoding and processing
+- floating-point stream/music decoding, DSP, FX, and recording
+
+* 3D sound
+- play samples/streams/musics in any 3D position, with EAX support
+
+* Expandable
+- underlying DirectSound object interfaces are accessible
+
+* Small
+- BASS is under 100KB (on Windows), so won't bloat your distribution
+
+
+Using BASS
+==========
+There is no guarantee that all future BASS versions will be compatible
+with all previous versions, so your program should use BASS_GetVersion
+to check the version that is loaded. This also means that you should
+put the BASS module in the same directory as your executable (not just
+somewhere in the path), to avoid the possibility of a wrong version being
+loaded.
+
+If you are updating your software from a previous BASS version, then
+you should check the "History" section (below), to see if any of the
+functions that you are using have been affected by a change.
+
+Win32 version
+-------------
+C/C++, Visual Basic, Delphi and MASM APIs are provided, to use BASS with
+another language you'll first have to convert the header file. Or, as a
+last resort, you could use LoadLibrary and GetProcAddress.
+
+One benefit of the LoadLibrary method is that it allows you to look for
+the correct BASS version, because you can load and unload BASS.DLL at
+any time. This also allows those who'd prefer not to have a separate
+DLL to store it with the program (eg. in a resource), write it to disk,
+load it, use it, free it and delete it.
+
+The downside is that you have to manually import each function that you
+use, with the GetProcAddress function. But it has been made a lot simpler
+to import BASS this way by the use of the BASSDEF #define. Here's a small
+example:
+
+#define BASSDEF(f) (WINAPI *f) // define the functions as pointers
+#include "bass.h"
+...
+HINSTANCE bass=LoadLibrary("BASS.DLL"); // load BASS
+BASS_Init=GetProcAddress(bass,"BASS_Init"); // get BASS_Init
+BASS_Init(-1,44100,0,hWnd,NULL); // call BASS_Init
+
+See the LOADNGET.C file for a more complete example.
+
+To use BASS with Borland C++ Builder, you'll first have to create a
+Borland C++ Builder import library for it. This is done by using the
+IMPLIB tool that comes with Borland C++ Builder. Simply execute this:
+
+ IMPLIB BASSBCB.LIB BASS.DLL
+
+... and then use BASSBCB.LIB in your projects to import BASS.
+
+To use BASS with LCC-Win32, you'll first have to create a compatible
+import library for it. This is done by using the PEDUMP and BUILDLIB
+tools that come with LCC-Win32. Run these 2 commands:
+
+ PEDUMP /EXP BASS.LIB > BASSLCC.EXP
+ BUILDLIB BASSLCC.EXP BASSLCC.LIB
+
+... and then use BASSLCC.LIB in your projects to import BASS.
+
+For the BASS functions that return strings (char*), VB users should use
+the VBStrFromAnsiPtr function to convert the returned pointer into a VB
+string.
+
+MacOSX version
+--------------
+A separate "LIB" file is not required for OSX. Using XCode, you can simply
+add the DYLIB file to the project. Or using a makefile, you can build your
+programs like this, for example:
+
+ gcc yoursource -L. -lbass -o yourprog
+
+The LIBBASS.DYLIB file must be put in the same directory as the executable
+(it can't just be somewhere in the path). See the example makefiles.
+
+LIBBASS.DYLIB is a universal binary, with support for both PowerPC and
+Intel Macs. If you want PowerPC-only or Intel-only versions, the included
+makefile can create them for you, by typing "make ppc" or "make i386". It
+will also process any BASS add-ons placed in the same directory.
+
+
+Latest Version
+==============
+The latest version of BASS can always be found at the BASS website:
+
+ www.un4seen.com
+
+
+Copyright, disclaimer, and all that other jazz
+==============================================
+The BASS library is free for non-commercial use. If you are a non-
+commercial entity (eg. an individual) and are not charging for your
+product, and the product has no other commercial purpose, then you
+can use BASS in it for free. If you wish to use BASS in commercial
+products, then please also see the next section.
+
+TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BASS IS PROVIDED
+"AS IS", WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY
+AND/OR FITNESS FOR A PARTICULAR PURPOSE. THE AUTHORS SHALL NOT BE HELD
+LIABLE FOR ANY DAMAGE THAT MAY RESULT FROM THE USE OF BASS. BASICALLY,
+YOU USE BASS ENTIRELY AT YOUR OWN RISK.
+
+Usage of BASS indicates that you agree to the above conditions.

+
+
+BASS in commercial products?
+============================
+BASS is available for use in your commercial products. The licence
+types available are as follows:
+
+SHAREWARE: Allows the usage of BASS in an unlimited number of your
+shareware products, which must sell for no more than 40 Euros each.
+If you're an individual making and selling your own software (and
+its price is within the limit), this is the licence for you.
+
+SINGLE COMMERCIAL: Allows the usage of BASS in a single commercial
+product.
+
+UNLIMITED COMMERCIAL: Allows the usage of BASS in an unlimited number
+of your commercial products. This licence is on a per site basis. So
+if your company has two sites that use BASS, then two licences are
+required.
+
+Please note the products must be end-user products, eg. not components
+used by other products.
+
+These licences only cover your own software. not the publishing of
+other's software. If you publish other's software, its developers (or
+the software itself) will need to be licensed to use BASS.
+
+These licences are on a per-platform basis, with reductions available
+when licensing for both platforms. In all cases there are no royalties
+to pay, and you can use future BASS updates without further cost. One
+licence covers one person or entity and is not transferable.
+
+These licences do not allow reselling/sublicensing of BASS. For example,
+if a product is a development system, the users of said product are not
+licensed to use BASS in their productions - they will need their own
+licences.
+
+If the standard licences do not meet your requirements, or if you have
+any questions, please get in touch (email: bass@un4seen.com).

+
+MP3
+===
+MP3 technology is patented, and Thomson license the use of their and
+Fraunhofer's patents. The inclusion of an MP3 decoder (eg. BASS) in a
+commercial product requires an MP3 patent licence. Contact Thomson for
+details:
+
+ www.mp3licensing.com
+
+Alternatively, the "MP3-FREE" BASS version doesn't include its own MP3
+decoder but instead makes use of the operating system's already licensed
+decoder.
+
+NOTE: When using the OS's MP3 decoder, BASS still does the file handling
+ so all the usual features are still supported, including streaming,
+ tag reading, pre-scanning, gapless playback, etc...
+
+
+History
+=======
+These are the major (and not so major) changes at each version stage.
+There are of course bug fixes and other little improvements made along
+the way too! To make upgrading simpler, all functions affected by a

+ I did do a version of this as an object (see Rev 1.1) but it was getting too
+ complicated and I couldn't see any real benefits to it so I dumped it
+ for an ordinary memory buffer with pointers.
+
+ This unit is a bit C-like, everything is done with pointers and extensive
+ use is made of the undocumented feature of the Inc() function that
+ increments pointers by the size of the object pointed to.
+ All of this could probably be done using Pascal array notation with
+ range-checking turned off, but I'm not sure it's worth it.

+
+ if you think this component is nice and you use it, sent me a short email.
+ I've seen that other of my components have been downloaded a lot, but I've
+ got no clue wether they are actually used.
+ Don't worry because you are free to use these components
+
+ Timing has improved, however because the messages are handled by the normal
+ windows message loop (of the main window) it is still influenced by actions
+ done on the window (minimize/maximize ..).
+ Use of a second thread with higher priority which only handles the
+ timer message should increase performance. If somebody knows such a component
+ which is freeware please let me know.

+unit MidiIn;
+
+{
+ Properties:
+ DeviceID: Windows numeric device ID for the MIDI input device.
+ Between 0 and NumDevs-1.
+ Read-only while device is open, exception when changed while open
+
+ MIDIHandle: The input handle to the MIDI device.
+ 0 when device is not open
+ Read-only, runtime-only
+
+ MessageCount: Number of input messages waiting in input buffer
+
+ Capacity: Number of messages input buffer can hold
+ Defaults to 1024
+ Limited to (64K/event size)
+ Read-only when device is open (exception when changed while open)
+
+ SysexBufferSize: Size in bytes of each sysex buffer
+ Defaults to 10K
+ Minimum 0K (no buffers), Maximum 64K-1
+
+ SysexBufferCount: Number of sysex buffers
+ Defaults to 16
+ Minimum 0 (no buffers), Maximum (avail mem/SysexBufferSize)
+ Check where these buffers are allocated?
+
+ SysexOnly: True to ignore all non-sysex input events. May be changed while
+ device is open. Handy for patch editors where you have lots of short MIDI
+ events on the wire which you are always going to ignore anyway.
+
+ DriverVersion: Version number of MIDI device driver. High-order byte is
+ major version, low-order byte is minor version.
+
+ ProductName: Name of product (e.g. 'MPU 401 In')
+
+ MID and PID: Manufacturer ID and Product ID, see
+ "Manufacturer and Product IDs" in MMSYSTEM.HLP for list of possible values.
+
+ Methods:
+ GetMidiEvent: Read Midi event at the head of the FIFO input buffer.
+ Returns a TMyMidiEvent object containing MIDI message data, timestamp,
+ and sysex data if applicable.
+ This method automatically removes the event from the input buffer.
+ It makes a copy of the received sysex buffer and puts the buffer back
+ on the input device.
+ The TMyMidiEvent object must be freed by calling MyMidiEvent.Free.
+
+ Open: Opens device. Note no input will appear until you call the Start
+ method.
+
+ Close: Closes device. Any pending system exclusive output will be cancelled.
+
+ Start: Starts receiving MIDI input.
+
+ Stop: Stops receiving MIDI input.
+
+ Events:
+ OnMidiInput: Called when MIDI input data arrives. Use the GetMidiEvent to
+ get the MIDI input data.
+
+ OnOverflow: Called if the MIDI input buffer overflows. The caller must
+ clear the buffer before any more MIDI input can be received.
+
+ Notes:
+ Buffering: Uses a circular buffer, separate pointers for next location
+ to fill and next location to empty because a MIDI input interrupt may
+ be adding data to the buffer while the buffer is being read. Buffer
+ pointers wrap around from end to start of buffer automatically. If
+ buffer overflows then the OnBufferOverflow event is triggered and no
+ further input will be received until the buffer is emptied by calls
+ to GetMidiEvent.
+
+ Sysex buffers: There are (SysexBufferCount) buffers on the input device.
+ When sysex events arrive these buffers are removed from the input device and
+ added to the circular buffer by the interrupt handler in the DLL. When the sysex events
+ are removed from the circular buffer by the GetMidiEvent method the buffers are
+ put back on the input. If all the buffers are used up there will be no
+ more sysex input until at least one sysex event is removed from the input buffer.
+ In other words if you're expecting lots of sysex input you need to set the
+ SysexBufferCount property high enough so that you won't run out of
+ input buffers before you get a chance to read them with GetMidiEvent.
+
+ If the synth sends a block of sysex that's longer than SysexBufferSize it
+ will be received as separate events.
+ TODO: Component derived from this one that handles >64K sysex blocks cleanly
+ and can stream them to disk.
+
+ Midi Time Code (MTC) and Active Sensing: The DLL is currently hardcoded
+ to filter these short events out, so that we don't spend all our time
+ processing them.
+ TODO: implement a filter property to select the events that will be filtered
+ out.

+
+unit MidiOut;
+
+{
+ MIDI Output component.
+
+ Properties:
+ DeviceID: Windows numeric device ID for the MIDI output device.
+ Between 0 and (midioutGetNumDevs-1), or MIDI_MAPPER (-1).
+ Special value MIDI_MAPPER specifies output to the Windows MIDI mapper
+ Read-only while device is open, exception if changed while open
+
+ MIDIHandle: The output handle to the MIDI device.
+ 0 when device is not open
+ Read-only, runtime-only
+
+ ProductName: Name of the output device product that corresponds to the
+ DeviceID property (e.g. 'MPU 401 out').
+ You can write to this while the device is closed to select a particular
+ output device by name (the DeviceID property will change to match).
+ Exception if this property is changed while the device is open.
+
+ Numdevs: Number of MIDI output devices installed on the system. This
+ is the value returned by midiOutGetNumDevs. It's included for
+ completeness.
+
+ Technology: Type of technology used by the MIDI device. You can set this
+ property to one of the values listed for OutportTech (below) and the component
+ will find an appropriate MIDI device. For example:
+ MidiOutput.Technology := opt_FMSynth;
+ will set MidiInput.DeviceID to the MIDI device ID of the FM synth, if one
+ is installed. If no such device is available an exception is raised,
+ see MidiOutput.SetTechnology.
+
+ See the MIDIOUTCAPS entry in MMSYSTEM.HLP for descriptions of the
+ following properties:
+ DriverVersion
+ Voices
+ Notes
+ ChannelMask
+ Support
+
+ Error: The error code for the last MMSYSTEM error. See the MMSYSERR_
+ entries in MMSYSTEM.INT for possible values.
+
+ Methods:
+ Open: Open MIDI device specified by DeviceID property for output
+
+ Close: Close device
+
+ PutMidiEvent(Event:TMyMidiEvent): Output a note or sysex message to the
+ device. This method takes a TMyMidiEvent object and transmits it.
+ Notes:
+ 1. If the object contains a sysex event the OnMidiOutput event will
+ be triggered when the sysex transmission is complete.
+ 2. You can queue up multiple blocks of system exclusive data for
+ transmission by chucking them at this method; they will be
+ transmitted as quickly as the device can manage.
+ 3. This method will not free the TMyMidiEvent object, the caller
+ must do that. Any sysex data in the TMyMidiEvent is copied before
+ transmission so you can free the TMyMidiEvent immediately after
+ calling PutMidiEvent, even if output has not yet finished.
+
+ PutShort(MidiMessage: Byte; Data1: Byte; Data2: Byte): Output a short
+ MIDI message. Handy when you can't be bothered to build a TMyMidiEvent.
+ If the message you're sending doesn't use Data1 or Data2, set them to 0.
+
+ PutLong(TheSysex: Pointer; msgLength: Word): Output sysex data.

+Midi components
+ TMidiFile, TMidiScope
+ TMidiIn and TMidiOut of david Churcher are included because they are used in
+ the demo application
+
+Freeware.
+
+100% source code, demo application.
+
+Included Components/Classes
+
+TMidiFile, read a midifile and have the contents available in memory
+ list of Tracks, track is list of events
+
+
+TMidiScope, show all activity on a midi device
+
+TMidiIn and TMidiOut of David Churcher are included because they are used
+in the demo application
+
+Midiplayer is a demo application which plays a midifile on a midi output
+ it is build fairly simple with the included components. The timer is used
+ to time the midievents. The timing is therefor as good as the windows timer.
+
+
+ The header of midifile,midiscope contains help information on the properties/functions
+ The example Midiplayer gives a good idea how to use the components
+
+Installation
+ open midiComp.dpk with file/open
+ compile and install the package
+ make sure that the directory where the files are located is in the library path
+ (tools/environment options/library)
+
+to run the demo
+ open project1.dpr in the demo directory and press run.
+

+{ ZLPortIO driver interface unit v1.20 }
+{ -----------------------------------------------------------------------------}
+{ Description: }
+{ This unit allow your application direct access port input and output under }
+{ all versions of Microsoft Windows® }
+{ Depends: }
+{ zlportio.sys ddkint.pas }
+{ You must distribute zlportio.sys with your application }
+{ Procedures and functions: }
+{ procedure zlioportread( const Port,DataType:dword ):dword; }
+{ procedure zlioportwrite( const Port,DataType,Data:dword ); }
+{ }
+{ function portreadb( const Port:dword ):byte; }
+{ function portreadw( const Port:dword ):word; }
+{ function portreadl( const Port:dword ):dword; }
+{ }
+{ procedure portwriteb( const Port:Dword;const Data:byte ); }
+{ procedure portwritew( const Port:dword;const Data:word ); }
+{ procedure portwritel( const Port,Data:dword ); }
+{ }
+{ Examples: }
+{ // get data bits from LPT port }
+{ databits := portreadb( $378 ) }
+{ // set data bits from LPT port }
+{ portwriteb( $378, databits ) }
+{ // The second parameter determine the databus length for operation }
+{ -----------------------------------------------------------------------------}
+{ Revision History: }
+{ 1.00: + First public release }
+{ 1.10: + Added new functions (portreadX,portwriteX) for convenience of usage }
+{ 1.20: + Added new function (zliosetiopm) for enabling direct access to ports}
+{ 1.30: + added compiler directives for correct compilation }
+{ 1.40: + added opportunity to run multiply instances client to driver }
+{ 1.50: - fixed bug with work under win98 }
