Kenneth,

Just a thought, but have you tried drawing your text, outline, and
shadow onto a YUV/A surface, and using blendregion?  I think that may
be the best way to do what you're doing.  As far as the grey around
the edges goes, I'm not really sure what's happening there - I didn't
do a lot of testing with colored text, I pretty much dropped all of
the blend functions into place and tried them in mythtv once I'd
stomped all of the blatant bugs in them, and mythtv doesn't use
colored text, sooooooo... :-/

BTW, any idea if theming the CC text is also a possibility?  I'd love
to see CC text drawn outlined, w/o a background - look at how tvtime
does it for an idea of what I'm talking about ;-)
