Make sure I understand your comment - you don't like the fact that I call
vo_init and then use the vo_screenheight and vo_screenwidth values?  This
is how the old version managed fullscreen.

I did only really think about xv and xmga output...

Your proposal is that this should be in two parts - in mplayer.c to
scale input to "square pixel", and then in the vo drivers themselves
rescale to account for any non-square display resolution?
