+ 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
