This change enables multisampled clipping for mixed sampled render targets. Previously clipping in mixed samples config behaved the same as in the gpu config. In order to retrofit non-MSAA draw methods, programmable sample locations are used in order to colocate all samples at (0.5, 0.5). Requires support for NV_sample_locations.
