So sure, for GPU limited cases this won't help a lot - however, typical java2d 
is usually CPU limited with tons of very small primitives and many state

It does not affect so much the xrender which do the same CPU related steps, but 
this speeds up so !much! OGL if executed in parallel.
I think the benchmark is cheating here, it does not call XSync nor glflush for 
each operation, so it just checks the speed of pushing the data to the buffer, 
and not measured the actual rendering for both pipelines, unlike the 
software-based rendering.
