David Reveman has just posted a fascinating patch that debuts the support of pixel shaders in Moonlight.
David's patch uses Gallium, and he says:
The current implementation uses gallium's softpipe driver but hooking up the llvm driver as well should be a minor task and give significantly better software performance.
My current approach is to focus on getting all these things working in software first. By using a OpenVG backend for cairo we can incrementally move to using gallium and hardware for all rendering.
