+This is the based on the SDL ( http://www.libsdl.org ) headers, and has been converted, comments and all, to the Pascal unit called sdl.pas.
+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.
+ Rbert Kisnmeth, 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 . 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
+ to get the values for X, Y, and Z. To find the proper signs we note
+ that:

+ 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.

+Delphi interface unit for OpenGL version 1.2 compilable with Delphi 3-6 and Kylix.
+
+This unit is open source under the Mozilla Public License and
+the original author is Dipl. Ing. Mike Lischke (public@lischke-online.de).
+
+You can obtain this unit also from the JEDI (Joint Endeavor of Delphi Innovators)
+API page at www.delphi-jedi.org.
+
+Note for GLScene users: Eric Grange has provided a general vector types unit which
+resolves conflicts for types which are defined in OpenGL12.pas as well as Geometry.pas.
+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.
+
+Have fun and
+

+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.

+{
+ $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.

+{
+ Simple classes for using SQLite's exec and get_table.
+
+ TSQLiteDatabase wraps the calls to open and close an SQLite database.
+ It also wraps SQLite_exec for queries that do not return a result set
+
+ TSQLiteTable wraps execution of SQL query.
+ It run query and read all returned rows to internal buffer.
+ It allows accessing fields by name as well as index and can move through a
+ result set forward and backwards, or randomly to any row.
+
+ TSQLiteUniTable wraps execution of SQL query.
+ It run query as TSQLiteTable, but reading just first row only!
+ You can step to next row (until not EOF) by 'Next' method.
+ You cannot step backwards! (So, it is called as UniDirectional result set.)
+ It not using any internal buffering, this class is very close to Sqlite API.
+ It allows accessing fields by name as well as index on actual row only.
+ Very good and fast for sequentional scanning of large result sets with minimal
+ memory footprint.
+
+ Warning! Do not close TSQLiteDatabase before any TSQLiteUniTable,
+ because query is closed on TSQLiteUniTable destructor and database connection
+ is used during TSQLiteUniTable live!
+
+ SQL parameter usage:
+ You can add named parameter values by call set of AddParam* methods.
+ Parameters will be used for first next SQL statement only.
+ Parameter name must be prefixed by ':', '$' or '@' and same prefix must be
+ used in SQL statement!
+ Sample:
+ table.AddParamText(':str', 'some value');
+ s := table.GetTableString('SELECT value FROM sometable WHERE id=:str');
+
+ Notes from Andrew Retmanski on prepared queries
+ The changes are as follows:
+
+ SQLiteTable3.pas
+ - Added new boolean property Synchronised (this controls the SYNCHRONOUS pragma as I found that turning this OFF increased the write performance in my application)
+ - Added new type TSQLiteQuery (this is just a simple record wrapper around the SQL string and a TSQLiteStmt pointer)
+ - Added PrepareSQL method to prepare SQL query - returns TSQLiteQuery
+ - Added ReleaseSQL method to release previously prepared query
+ - Added overloaded BindSQL methods for Integer and String types - these set new values for the prepared query parameters
+ - Added overloaded ExecSQL method to execute a prepared TSQLiteQuery
+
+ Usage of the new methods should be self explanatory but the process is in essence:
+
+ 1. Call PrepareSQL to return TSQLiteQuery 2. Call BindSQL for each parameter in the prepared query 3. Call ExecSQL to run the prepared query 4. Repeat steps 2 & 3 as required 5. Call ReleaseSQL to free SQLite resources
+
+ One other point - the Synchronised property throws an error if used inside a transaction.

+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 reformatted to better look (official borland formatting 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
+
+21 Dec 2004 First public release

+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, with both "push" and "pull" systems
+
+* File streams
+ MP3/MP2/MP1/OGG/WAV/AIFF file streaming
+
+* Internet file streaming
+ stream files from the internet, including Shout/Icecast
+
+* User file streaming
+ stream 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 MOD musics can be outputted in any way you want
+
+* Speaker assignment
+ assign streams and MOD musics to specific speakers
+
+* High precision synchronization
+ synchronize events in your software to the streams and MOD musics
+
+* 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
+
+* 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.
+
+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
+
+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:

+
+
+Licence
+=======
+BASS is free for non-commercial use. If you are a non-commercial entity
+(eg. an individual) and you 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. YOU USE
+BASS ENTIRELY AT YOUR OWN RISK.
+
+Usage of BASS indicates that you agree to the above conditions.
+
+All trademarks and other registered names contained in the BASS
+package are the property of their respective owners.
+
+Commercial licensing
+--------------------
+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 are an individual (not a corporation) 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).
+
+Visit the BASS website for the latest pricing:
+

+
+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 does not 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
+change to the BASS interface are listed.

+
+5. On OS X you have to patch the the dylibs. Run the following
+ script. It patches the dylibs and copies them to the
+ lib/ffmpeg dir:
+
+./copy_and_patch_dylibs.sh
+
+You're done.

+Fast Fourier Transform routines.
+
+ This file contains a few FFT routines, including a real-FFT
+ routine that is almost twice as fast as a normal complex FFT,
+ and a power spectrum routine when you know you don't care
+ about phase information.
+
+ Some of this code was based on a free implementation of an FFT
+ by Don Cross, available on the web at:
+
+ http://www.intersrv.com/~dcross/fft.html
+
+ The basic algorithm for his code was based on Numerican Recipes
+ in Fortran. I optimized his code further by reducing array
+ accesses, caching the bit reversal table, and eliminating
+ float-to-double conversions, and I added the routines to
+ calculate a real FFT and a real power spectrum.
+
+***********************************************************************

+ Salvo Ventura - November 2006
+ Added more window functions:
+ * 4: Blackman
+ * 5: Blackman-Harris
+ * 6: Welch

+ * 9: Gaussian(a=4.5)

+ * @enum:
+ * FT_LOAD_XXX
+ *
+ * @description:
+ * A list of bit-field constants, used with @FT_Load_Glyph to indicate
+ * what kind of operations to perform during glyph loading.
+ *
+ * @values:
+ * FT_LOAD_DEFAULT ::
+ * Corresponding to 0, this value is used a default glyph load. In this
+ * case, the following will happen:
+ *
+ * 1. FreeType looks for a bitmap for the glyph corresponding to the
+ * face's current size. If one is found, the function returns. The
+ * bitmap data can be accessed from the glyph slot (see note below).
+ *
+ * 2. If no embedded bitmap is searched or found, FreeType looks for a
+ * scalable outline. If one is found, it is loaded from the font
+ * file, scaled to device pixels, then "hinted" to the pixel grid in
+ * order to optimize it. The outline data can be accessed from the
+ * glyph slot (see note below).
+ *
+ * Note that by default, the glyph loader doesn't render outlines into
+ * bitmaps. The following flags are used to modify this default
+ * behaviour to more specific and useful cases.
+ *
+ * FT_LOAD_NO_SCALE ::
+ * Don't scale the vector outline being loaded to 26.6 fractional
+ * pixels, but kept in font units. Note that this also disables
+ * hinting and the loading of embedded bitmaps. You should only use it
+ * when you want to retrieve the original glyph outlines in font units.
+ *
+ * FT_LOAD_NO_HINTING ::
+ * Don't hint glyph outlines after their scaling to device pixels.
+ * This generally generates "blurrier" glyphs in anti-aliased modes.
+ *
+ * This flag is ignored if @FT_LOAD_NO_SCALE is set.
+ *
+ * FT_LOAD_RENDER ::
+ * Render the glyph outline immediately into a bitmap before the glyph
+ * loader returns. By default, the glyph is rendered for the
+ * @FT_RENDER_MODE_NORMAL mode, which corresponds to 8-bit anti-aliased
+ * bitmaps using 256 opacity levels. You can use either
+ * @FT_LOAD_TARGET_MONO or @FT_LOAD_MONOCHROME to render 1-bit
+ * monochrome bitmaps.
+ *
+ * This flag is ignored if @FT_LOAD_NO_SCALE is set.
+ *
+ * FT_LOAD_NO_BITMAP ::
+ * Don't look for bitmaps when loading the glyph. Only scalable
+ * outlines will be loaded when available, and scaled, hinted, or
+ * rendered depending on other bit flags.
+ *
+ * This does not prevent you from rendering outlines to bitmaps
+ * with @FT_LOAD_RENDER, however.
+ *
+ * FT_LOAD_VERTICAL_LAYOUT ::
+ * Prepare the glyph image for vertical text layout. This basically
+ * means that `face.glyph.advance' will correspond to the vertical
+ * advance height (instead of the default horizontal advance width),
+ * and that the glyph image will be translated to match the vertical
+ * bearings positions.
+ *
+ * FT_LOAD_FORCE_AUTOHINT ::
+ * Force the use of the FreeType auto-hinter when a glyph outline is
+ * loaded. You shouldn't need this in a typical application, since it
+ * is mostly used to experiment with its algorithm.
+ *
+ * FT_LOAD_CROP_BITMAP ::
+ * Indicates that the glyph loader should try to crop the bitmap (i.e.,
+ * remove all space around its black bits) when loading it. This is
+ * only useful when loading embedded bitmaps in certain fonts, since
+ * bitmaps rendered with @FT_LOAD_RENDER are always cropped by default.
+ *
+ * FT_LOAD_PEDANTIC ::
+ * Indicates that the glyph loader should perform pedantic
+ * verifications during glyph loading, rejecting invalid fonts. This
+ * is mostly used to detect broken glyphs in fonts. By default,
+ * FreeType tries to handle broken fonts also.
+ *
+ * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+ * Indicates that the glyph loader should ignore the global advance
+ * width defined in the font. As far as we know, this is only used by
+ * the X-TrueType font server, in order to deal correctly with the
+ * incorrect metrics contained in DynaLab's TrueType CJK fonts.
+ *
+ * FT_LOAD_NO_RECURSE ::
+ * This flag is only used internally. It merely indicates that the
+ * glyph loader should not load composite glyphs recursively. Instead,
+ * it should set the `num_subglyph' and `subglyphs' values of the glyph
+ * slot accordingly, and set "glyph->format" to
+ * @FT_GLYPH_FORMAT_COMPOSITE.
+ *
+ * The description of sub-glyphs is not available to client
+ * applications for now.
+ *
+ * FT_LOAD_IGNORE_TRANSFORM ::
+ * Indicates that the glyph loader should not try to transform the
+ * loaded glyph image. This doesn't prevent scaling, hinting, or
+ * rendering.
+ *
+ * FT_LOAD_MONOCHROME ::
+ * This flag is used with @FT_LOAD_RENDER to indicate that you want
+ * to render a 1-bit monochrome glyph bitmap from a vectorial outline.
+ *
+ * Note that this has no effect on the hinting algorithm used by the
+ * glyph loader. You should better use @FT_LOAD_TARGET_MONO if you
+ * want to render monochrome-optimized glyph images instead.
+ *
+ * FT_LOAD_LINEAR_DESIGN ::
+ * Return the linearly scaled metrics expressed in original font units
+ * instead of the default 16.16 pixel values.
+ *
+ * FT_LOAD_NO_AUTOHINT ::
+ * Indicates that the auto-hinter should never be used to hint glyph
+ * outlines. This doesn't prevent native format-specific hinters from
+ * being used. This can be important for certain fonts where unhinted
+ * output is better than auto-hinted one.
+ *
+ * FT_LOAD_TARGET_NORMAL ::
+ * Use hinting for @FT_RENDER_MODE_NORMAL.
+ *
+ * FT_LOAD_TARGET_LIGHT ::
+ * Use hinting for @FT_RENDER_MODE_LIGHT.
+ *
+ * FT_LOAD_TARGET_MONO ::

+ (* *)
+ (* num_faces :: In the case where the face is located in a *)
+ (* collection (i.e., a file which embeds *)
+ (* several faces), this is the total number of *)
+ (* faces found in the resource. 1 by default. *)
+ (* Accessing non-existent face indices causes *)
+ (* an error. *)
+ (* *)
+ (* face_index :: The index of the face in its font file. *)
+ (* Usually, this is 0 for all normal font *)
+ (* formats. It can be > 0 in the case of *)
+ (* collections (which embed several fonts in a *)
+ (* single resource/file). *)
+ (* *)
+ (* face_flags :: A set of bit flags that give important *)
+ (* information about the face; see the *)
+ (* @FT_FACE_FLAG_XXX constants for details. *)
+ (* *)
+ (* style_flags :: A set of bit flags indicating the style of *)
+ (* the face (i.e., italic, bold, underline, *)
+ (* etc). See the @FT_STYLE_FLAG_XXX *)
+ (* constants. *)
+ (* *)
+ (* num_glyphs :: The total number of glyphs in the face. *)
+ (* *)
+ (* family_name :: The face's family name. This is an ASCII *)
+ (* string, usually in English, which describes *)
+ (* the typeface's family (like `Times New *)
+ (* Roman', `Bodoni', `Garamond', etc). This *)
+ (* is a least common denominator used to list *)
+ (* fonts. Some formats (TrueType & OpenType) *)
+ (* provide localized and Unicode versions of *)
+ (* this string. Applications should use the *)
+ (* format specific interface to access them. *)
+ (* *)
+ (* style_name :: The face's style name. This is an ASCII *)
+ (* string, usually in English, which describes *)
+ (* the typeface's style (like `Italic', *)
+ (* `Bold', `Condensed', etc). Not all font *)
+ (* formats provide a style name, so this field *)
+ (* is optional, and can be set to NULL. As *)
+ (* for `family_name', some formats provide *)
+ (* localized/Unicode versions of this string. *)
+ (* Applications should use the format specific *)
+ (* interface to access them. *)
+ (* *)
+ (* num_fixed_sizes :: The number of fixed sizes available in this *)
+ (* face. This should be set to 0 for scalable *)
+ (* fonts, unless its face includes a set of *)
+ (* glyphs (called a `strike') for the *)
+ (* specified sizes. *)
+ (* *)

+ (* bitmap/graymap sizes that are contained in *)
+ (* in the font face. Should be set to NULL if *)
+ (* the field `num_fixed_sizes' is set to 0. *)
+ (* *)
+ (* num_charmaps :: The total number of character maps in the *)
+ (* face. *)
+ (* *)
+ (* charmaps :: A table of pointers to the face's charmaps. *)
+ (* Used to scan the list of available charmaps *)
+ (* -- this table might change after a call to *)
+ (* @FT_Attach_File or @FT_Attach_Stream (e.g. *)

+ (* CMap to the face object). *)
+ (* *)
+ (* generic :: A field reserved for client uses. See the *)
+ (* @FT_Generic type description. *)
+ (* *)
+ (* bbox :: The font bounding box. Coordinates are *)
+ (* expressed in font units (see units_per_EM). *)
+ (* The box is large enough to contain any *)
+ (* glyph from the font. Thus, bbox.yMax can *)
+ (* be seen as the `maximal ascender', *)

+ (* `bbox.xMax-bbox.xMin' (not to be confused *)
+ (* with the maximal _advance_width_). Only *)
+ (* relevant for scalable formats. *)
+ (* *)
+ (* units_per_EM :: The number of font units per EM square for *)
+ (* this face. This is typically 2048 for *)
+ (* TrueType fonts, 1000 for Type1 fonts, and *)
+ (* should be set to the (unrealistic) value 1 *)
+ (* for fixed-sizes fonts. Only relevant for *)
+ (* scalable formats. *)
+ (* *)
+ (* ascender :: The face's ascender is the vertical *)
+ (* distance from the baseline to the topmost *)
+ (* point of any glyph in the face. This *)
+ (* field's value is positive, expressed in *)
+ (* font units. Some font designs use a value *)
+ (* different from `bbox.yMax'. Only relevant *)
+ (* for scalable formats. *)
+ (* *)
+ (* descender :: The face's descender is the vertical *)
+ (* distance from the baseline to the *)
+ (* bottommost point of any glyph in the face. *)
+ (* This field's value is *negative* for values *)
+ (* below the baseline. It is expressed in *)
+ (* font units. Some font designs use a value *)
+ (* different from `bbox.yMin'. Only relevant *)
+ (* for scalable formats. *)
+ (* *)
+ (* height :: The face's height is the vertical distance *)
+ (* from one baseline to the next when writing *)
+ (* several lines of text. Its value is always *)
+ (* positive, expressed in font units. The *)
+ (* value can be computed as *)
+ (* `ascender+descender+line_gap' where the *)
+ (* value of `line_gap' is also called *)
+ (* `external leading'. Only relevant for *)
+ (* scalable formats. *)
+ (* *)
+ (* max_advance_width :: The maximal advance width, in font units, *)
+ (* for all glyphs in this face. This can be *)
+ (* used to make word wrapping computations *)
+ (* faster. Only relevant for scalable *)
+ (* formats. *)
+ (* *)
+ (* max_advance_height :: The maximal advance height, in font units, *)
+ (* for all glyphs in this face. This is only *)
+ (* relevant for vertical layouts, and should *)

+ (* not provide vertical metrics. Only *)
+ (* relevant for scalable formats. *)
