that's true. well i'll happily donate code if anyone wants to use it... but the
software isn't the real issue i guess - well from my point of view it's that
i've already solved software rendering. next is to actually support hardware
acceleration, but if that basically decelerates.. it's not a very attractive way
to spend my time :) Basically I've written a bit of a bench marker now that uses
XRender and compares to my own software implementation, so there's a fence post
to gauge by. I hope it helps driver authors in being able to test their work :)
I'll probably have to go the OpenGL route anyway now :)
