This patch fixes two minor problems the vo_xv driver has:
1. Starting in fullscreen e.g. (mplayer -fs dvd://1) will have a window
which doesn't extend all the way down the screen unless you have a 4:3
movie.
2. Monitoraspect is not used so e.g. showing a movie when in 1280x1024
desktop looks wrong.
BTW: maybe vo_xv.c should be reindented. it's getting more and more
unreadable
