Actualy, i'd like to change the way how OSD is drawn totaly.
The reason is, that the current system is very limted, we only support
b/w (YA) subs and only text with no positioning code.

What i'd like to have is something that can draw any colour at any
position into the video. The problem with this is, that it has to be
done at some point with a vf as i dont see any way how it could be done
with hw acceleration w/o being a big hack on most vo drivers.
But, fidling with the video stream also means that it will be a major
slowdown even if done the right way.

Has someone (Rich ? Alex ?) an idea how this can be done in a fast way
w/o more than 50% speed los compared to the current system ?
