also SET sw/hw scaling and osd support flags, and flip,
and accept_stride if you implement put_image (see vfcaps.h)

NOTE: VOCTRL_QUERY_FORMAT may be called _before_ first config()
but is always called between preinit() and uninit()
VOCTRL_GET_IMAGE
libmpcodecs Direct Rendering interface
You need to update mpi (mp_image.h) structure, for example,
look at vo_x11, vo_sdl, vo_xv or mga_common.
VOCTRL_PUT_IMAGE
VOCTRL_DRAW_IMAGE
replacement for the current draw_slice/draw_frame way of
passing video frames. by implementing SET_IMAGE, you'll get
image in mp_image struct instead of by calling draw_*.
unless you return VO_TRUE for VOCTRL_PUT_IMAGE call, the
unless you return VO_TRUE for VOCTRL_DRAW_IMAGE call, the
old-style draw_* functils will be called!
Note: draw_slice is still mandatory, for per-slice rendering!
VOCTRL_RESET - reset the video device
@ -88,7 +88,7 @@ Each vo driver _has_ to implement these:
draw_frame(): this is the older interface, this displays only complete
frames, and can do only packed format (YUY2, RGB/BGR).
Win32 codecs use this (DivX, Indeo, etc).
If you implement VOCTRL_PUT_IMAGE, you can left draw_frame.
If you implement VOCTRL_DRAW_IMAGE, you can left draw_frame.
draw_osd(): this displays subtitles and OSD.
It's a bit tricky to use it, since it's a callback-style stuff.
