-{ for GnuPascal, VirtualPascal, TMT and obviously }
-{ continue support for Delphi Kylix and FreePascal. }

-{ April 24 2003 - DL : under instruction from Alexey Barkovoy, I have added}

-{ from Prof. Abimbola Olowofoyeku (The African Chief),}
-{ I have added better Gnu Pascal support }
-{ }
-{ April 30 2003 - DL : under instruction from David Mears AKA }
-{ Jason Siletto, I have added FPC Linux support. }

- Revision 1.19 2007/12/05 22:54:20 savage
- Better Mac OS X support for Frameworks.
-
- Revision 1.18 2007/06/01 11:16:33 savage
- Added IFDEF UNIX for Workaround.
-
- Revision 1.17 2007/06/01 08:38:21 savage
- Added TTF_RenderText_Solid workaround as suggested by Michalis Kamburelis
-
- Revision 1.16 2007/05/29 21:32:14 savage
- Changes as suggested by Almindor for 64bit compatibility.
-
- Revision 1.15 2007/05/20 20:32:45 savage
- Initial Changes to Handle 64 Bits
-
- Revision 1.14 2006/12/02 00:19:01 savage
- Updated to latest version
-
- Revision 1.13 2005/04/10 11:48:33 savage
- Changes as suggested by Michalis, thanks.
-
- Revision 1.12 2005/01/05 01:47:14 savage
- Changed LibName to reflect what MacOS X should have. ie libSDL*-1.2.0.dylib respectively.
-
- Revision 1.11 2005/01/04 23:14:57 savage
- Changed LibName to reflect what most Linux distros will have. ie libSDL*-1.2.so.0 respectively.
-
- 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
