I have implemented the switches like stated here (not yet uploaded to CVS),
but I think it would be better to reverse -vm and -zoom, because you usually
want modeswitching and scaling (I check -zoom for hardware scaling, too), so
it would be better to have -novm and -nozoom switches instead.
Also the current screenmode should be passed to the init() function so they
don't have to repeat the code from x11_common.c, this is usefull for cases
where the no modeswitching is wanted.
How about passing screenwidth, screenheight and screenbpp to the
vidout-plugins init()?
(Values stored in vo_something in x11_common.c)
