* 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, as such had to remove the non-blanking
* console mode. Supports hardware zoom/reduce zoom modes.
* buffer. Added double-buffering. Supports hardware zoom/reduce zoom modes.
*
* Hints and tricks:
* - Use -dr to get direct rendering
* - Use -vop 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.
