Added BGR support. Removed lots of dud code. - * 10/04/02: Changed the memcpy functions to mem2agpcpy.. should be a tad - * faster. - * 11/04/02: Added a compile option so you can watch the film with the console - * as the background, or not. - * 13/04/02: Fix rough OSD stuff by rendering it straight onto the output - * buffer. Added double-buffering. Supports hardware zoom/reduce zoom modes. - * 13/04/02: Misc cleanups of the code. - * 22/10/02: Added geometry support to it - * - * Hints and tricks: - * - Use -dr to get direct rendering - * - Use -vf yuy2 to get yuy2 rendering, *MUCH* faster than yv12 - * - To get a black background and nice smooth OSD, use -double - * - To get the console as a background, but with scaled OSD, use -nodouble - * - The driver supports both scaling and shrinking the image using the -x and - * -y options on the mplayer commandline.
