 * Merged new video code from branch back to the trunk.
 *
 * Revision 1.4.6.1  2005/07/17 09:27:08  rjongbloed
 * Major revisions of the PWLib video subsystem including:
 *   removal of F suffix on colour formats for vertical flipping, all done with existing bool
 *   working through use of RGB and BGR formats so now consistent
 *   cleaning up the plug in system to use virtuals instead of pointers to functions.
 *   rewrite of SDL to be a plug in compatible video output device.
 *   extensive enhancement of video test program
 *
 * Revision 1.4  2005/01/31 08:05:41  csoutheren
 * More patches for MacOSX, thanks to Hannes Friederich
 *
 * Revision 1.3  2005/01/11 06:57:15  csoutheren
 * Fixed namespace collisions with plugin starup factories
 *
 * Revision 1.2  2005/01/04 08:09:42  csoutheren
 * Fixed Linux configure problems
 *
 * Revision 1.1  2005/01/04 07:44:03  csoutheren
