VMWare folk -- is this going to be easy to > add? Or do I need to add a new PIPE_CAP? Note the d3d equivalent (sample_info) is d3d10.1 and svga3d opcodes only cover d3d10, so yes this isn't doable. So I guess for the time being, either a cap bit or emulation (stick it into a uniform) should be done, though Brian probably knows better.
