There's some content out there in the wild where PlayRes and video 
aspect ratio (assuming 1:1 PAR) don't match, and this patch fixes the 
strangely stretched fonts with this material. I don't see how this hurts 
until libass gets PAR compensation.

Regarding PAR compensation, i wonder where I can get the necessary 
information (video aspect ratio) from in MPlayer.

BTW, how are "legacy" subs supposed to be handled, which assume 1:1 PAR 
and maybe even stretched the fonts manually (\fsx, \fsy) to get it to 
look right?
