[MPlayer-dev-eng] Patch to position full screen window on TV out

[Andrew de Quincey]

Hi, first of all, the rationale for this patch. I have a Nvidia Geforce4 with TV out. I've set it up as a second screen 
under XWindows, running at 800x600. I have a Sony widescreen TV. I have no window manager running on that 
screen.

Problem: when I use mplayer, I lose 1.5 centimetres on both sides of the screen. The card uses the CENTRE of 
the 800x600 screen. Now, I could spend hours messing with modelines (in fact I have, but nvidia's driver seems 
to be a little odd with the TV out modes). I've also messed with the nv-tv-out project, but this randomly crashes 
my machine, and is a bit over the top for what I want to do.

I can control the fullscreen size with "-screenh", "-screenw", but I can't centre it in the screen. That is what this 
patch does; adds "-screenxpos", "-screenypos" parameters used to position the fullscreen window.

I HAVE tried "-geometry", "-x", "-y", "-xy", using windowed mode, and the like, but these do not solve my problem.
