The graphics hw is not just for compositing. It has custom logic for 
doing complex operations like polygon rendering, line drawing, 
antialiasing and much more. Right now it's sounds like these operations 
are being done on the CPU which is not designed for doing these

Then the CPU has to process every pixel. As far as I can see, the CPU 
shouldn't need to touch *any* pixels for the type of graphics I see in 

Can you write a demo to see how many polygons per second Self can 
render using it's current system? (stripping away everything but the 
demo itself)

I think that may be a good simple test of Self's rendering engine that 
we can compare to alternate techniques.
