* video_out_tdfxfb.c
*
* Copyright (C) Zeljko Stevanovic 2001, <zsteva@ptt.yu>
*
* Most code rewrited, move from /dev/3dfx to /dev/fb0 (kernel 2.4.?)
* add support for YUY2 and BGR16 format, remove all X11 DGA code.
* - add support for hardware accelerated OSD (buggy for now).
* work on BGR16 and YUY2 (VO_3DFX_METHOD == 2 only)
* [oct2001]
* - added hardware acceleration for OSD (does not look nice, but is faster)
* (for YV12 don't fork.)
* - fixed YV12 support for ffdivx, but on my cpu this is sllower of yuv2rgb()
* try to uncommenting '#define YV12_CONV_METH'
* - fast_memcpy() is sllower of memcpy() (why, i don't know)
