Interrested to write a simple FreeType based AVSubtitle renderer?

One old idea i had but never implemented was to build these bitmaps with
a raytracer from some font and a pretty texture, surely would beat the
crap out of FreeType :)
One could even go as far as make them trasparent and store the x,y
coordinates for each pixel from where the refracted light comes from.
Glass subtitles with accurate refraction and fast and simple too at runtime
