I noticed:
* it opens an empty blank window before resizing it to the video size
* it asks for -screenw and -screenh
* you need to ship SDL in your binary

CoreVideo supports YV12 planar in 10.6. I looked a little at adding that
to the vo, but didn't see what to do with shared buffer support.

Also gl and corevideo both do unnecessary picture copies on OS X -
gl's is due to not using EXT_client_storage and corevideo's is due to
calling memcpy_pic() to draw OSD stuff instead of using EOSD.

gl's issue is easier, I think.
