Okay, so the memcopy's are taking up a little bit of time; still, the big  
win
so far is having the gpu render the font glyph based on just the outline  
data,
you're getting scalable fonts on the fly effectively for free.  This is  
seriously
cool.

That GPU gems link (  
http://http.developer.nvidia.com/GPUGems3/gpugems3_ch25.html )
referenced in your code is a good explanation.  Shaders kind of break my  
brain,
I'm glad to see this one in and working.
