+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]
+
+ Adding the three equations, we get:

+ 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 1.2 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 1.3 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 1.3 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

+ $Log: glut.pas,v $
+ 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.

+// function InitOpenGLFromLibrary(GL_Name, GLU_Name: String): Boolean;

+// Result: True if successful, False otherwise.

+// function CreateRenderingContext(DC: HDC; Options: TRCOptions; ColorBits, StencilBits, AccumBits, AuxBuffers: Integer;
+// Layer: Integer; var Palette: HPALETTE): HGLRC;

+// given parameters:
+// DC - the device context for which the rc is to be created
+// Options - options for the context, which the application would like to have
+// (it is not guaranteed they will be available)
+// ColorBits - the color depth of the device context (Note: Because of the internal DC handling of the VCL you
+// should avoid using GetDeviceCaps for memory DCs which are members of a TBitmap class.
+// Translate the Pixelformat member instead!)
+// StencilBits - requested size of the stencil buffer
+// AccumBits - requested size of the accumulation buffer
+// AuxBuffers - requested number of auxiliary buffers
+// Layer - ID for the layer for which the RC will be created (-1..-15 for underlay planes, 0 for main plane,
+// 1..15 for overlay planes)
+// Note: The layer handling is not yet complete as there is very few information
+// available and (until now) no OpenGL implementation with layer support on the low budget market.
+// Hence use 0 (for the main plane) as layer ID.
+// Palette - Palette Handle created within function (need to use DeleteObject(Palette) to free this if <> 0)
+// Result: the newly created context or 0 if setup failed
+//
+// procedure ActivateRenderingContext(DC: HDC; RC: HGLRC);

+// Counterpart to ActivateRenderingContext.
+//
+// procedure DestroyRenderingContext(RC: HGLRC);
+// RC will be destroyed and must be recreated if you want to use it again.
+//
+// procedure ReadExtensions;
+// Determines which extensions for the current rendering context are available and
+// loads their addresses. This procedure is called from ActivateRenderingContext
+// if a new pixel format is used, but you can safely call it from where you want
+// to actualize those values (under the condition that a rendering context MUST be
+// active).
+//
+// procedure ReadImplementationProperties;
+// Determines other properties of the OpenGL DLL (version, availability of extensions).
+// Again, a valid rendering context must be active.
+//
+// function HasActiveContext: Boolean;

+ Revision 1.2 2004/04/05 09:59:46 savage
+ Changes for FreePacal as suggested by Marco
+
+ Revision 1.1 2004/03/30 21:53:55 savage
+ Moved to it's own folder.
+
+ Revision 1.6 2004/02/20 17:26:19 savage
+ Extensions are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.5 2004/02/15 22:48:36 savage
+ More FPC and FreeBSD support changes.
+
+ 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 00:08:20 savage

+Note for GLScene users: Eric Grange has provided a general vector types unit which

+This unit is located in the sub folder "GLScene AddOn".
+Please add this unit to the uses clause of OpenGL12.pas and remove the few types which
+are already declared in VectorTypes.pas.
+
+For tests and as starting point three demos are included into the package. Two of them (GLDiag and GLTest)
+need the (also provided) simple OpenGL control GLControl (see "GLControl\Package").
+
+- Basic is a very simple test program which only uses an empty form.
+- GLTest (in GLControl) uses GLControl to show four rendering contexts simultanously.
+- GLDiag is a diagnosis tool similar to DXDiag which shows some properties of the current
+ OpenGL driver implementation.

+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
+===============================================================================================
+Change History, Version numbers
+-------------------------------
+The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order.
+Versions are counted from 1.0.0 beginning with the version from 2000-03-16.

+
+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

+
+ Revision 1.14 2004/12/23 23:42:18 savage
+ Applied Patches supplied by Michalis Kamburelis ( THANKS! ), for greater FreePascal compatability.
+
+ Revision 1.13 2004/09/30 22:31:59 savage
+ Updated with slightly different header comments
+
+ Revision 1.12 2004/09/12 21:52:58 savage
+ Slight changes to fix some issues with the sdl classes.
+
+ Revision 1.11 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.10 2004/07/20 23:57:33 savage
+ Thanks to Paul Toth for spotting an error in the SDL Audio Convertion structures.
+ In TSDL_AudioCVT the filters variable should point to and array of pointers and not what I had there previously.
+
+ Revision 1.9 2004/07/03 22:07:22 savage
+ Added Bitwise Manipulation Functions for TSDL_VideoInfo struct.
+
+ Revision 1.8 2004/05/10 14:10:03 savage

+
+ Revision 1.7 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 1.6 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 1.5 2004/02/22 15:32:10 savage
+ SDL_GetEnv Fix so it also works on FPC/Linux. Thanks to Rodrigo for pointing this out.

+ Revision 1.3 2004/02/18 22:35:51 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.

+ Revision 1.5 2004/06/02 19:38:53 savage
+ Changes to SDL_GradientFillRect as suggested by
+ Ángel Eduardo García Hernández. Many thanks.
+
+ Revision 1.4 2004/05/29 23:11:53 savage
+ Changes to SDL_ScaleSurfaceRect as suggested by
+ Ángel Eduardo García Hernández to fix a colour issue with the function. Many thanks.
+
+ Revision 1.3 2004/02/20 22:04:11 savage
+ Added Changes as mentioned by Rodrigo "Rui" R. (1/2 RRC2Soft) to facilitate FPC compilation and it also works in Delphi. Also syncronized the funcitons so that they are identical to sdlutils.pas, when no assembly version is available.
+
+ 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 1.7 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

+ 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.

+ Revision 1.10 2005/01/02 19:07:32 savage
+ Slight bug fix to use LongInt instead of Long ( Thanks Michalis Kamburelis )
+
+ Revision 1.9 2005/01/01 02:15:20 savage
+ Updated to v2.0.7
+
+ Revision 1.8 2004/10/07 21:02:32 savage
+ Fix for FPC
+
+ Revision 1.7 2004/09/30 22:39:50 savage
+ Added a true type font class which contains a wrap text function.
+ Changed the sdl_ttf.pas header to reflect the future of jedi-sdl.
+
+ 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 20:53:24 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 2004/02/16 22:16:40 savage
+ v1.0 changes
