vo_direct3d: dumb down OSD rendering

Render most of the OSD on the CPU, then draw it using a relatively
simple method. Do this for minimum code maintenance overhead. (While it
doesn't matter for vo_direct3d, and the effort spent here is probably
more than this would ever hope, I do hope to simplify the internal OSD
API for all these fringe VOs. Only vo_gpu should be allowed to do more
sophisticated things.)

If your GPU is shit (which it will be if you "want" to use vo_direct3d),
this might actually improve performance... is what I'd say, but out of
laziness a full screen sized texture gets uploaded on every OSD/subtitle
change, so maybe not.
