Okay maybe we should use this path, the only worry I have are in the guest around where we expose hw atomics to mesa, the limits and stuff were mostly designed around r600 level hw.

Had to fix a bunch of stuff until all piglit tests pass, but have so far found no problems with limits.

We might want to consider exposing GL_MAX_COMBINED_SHADER_OUTPUT_RESOURCES as a limit prior to using this.

Can you extend on this?
