Sure. The point is that if you can't use normalized coordinates at all on PIPE_TEXTURE_RECT, you can't implement OpenCL well on nv50 and r600. Hence, that should be allowed on OpenCL capable cards (and not on others). > r300 having to emit a shader instruction unconditionally in this case > really isn't that big of a deal. On nVidia cards, this doesn't matter, since they never prefer the normalization opposite to the OpenGL-required one. So if the maintainers of Radeon and software renderers, who might care, don't, I suppose we could as well not introduce the feature, even though I'm not totally convinced of this. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
