Right now, font sizes in libass are exactly like VSFilter's. Both scaling 
dependent on video height and this patch _unapplied_ are required to keep 
this compatibility. It is important, because SSA/ASS subtitles come with 
predefines font sizes, and it is natural to display them as they were 
intended to be displayed.

I could add an option to disable this compatibility hack, but is it really 
that important for font sizes to be exactly as in other applications ? And 
then, I won't be implementing size scaling with movie height or diagonal for 
quite some time. You think the patch is useful even without this ?
