Well the blt is just using SIMD... it's basically a "fast memcpy" and  
there's not much more than that.  You might want to look into cairo/ 
quartz.  I'm pretty sure cairo/quartz still uses pixman instead of CG  
for most of its opperations.  You may want to just hook into cairo if  
you want something higher level, too:
