  *  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)
