> Why is this needed? The second patch fixes format/type to mesa_format matching for intensity formats, so that texture uploads / buffer object clears / etc can get the memcpy paths. (Previously, we were testing on pixel format = GL_INTENSITY, which is nonsense and disallowed by earlier checks.) Unfortunately, the intensity mesa_formats are listed before their red equivalants in the formats, so we'd end up picking an intensity format for DrawPixels( GL_RED, ... If that happens, then the actual draw later in DrawPixels would write <I, I, I, I> to the destination, rather than <R, 0, 0, 1>. https://bugs.freedesktop.org/show_bug.cgi?id=76601 https://bugs.freedesktop.org/show_bug.cgi?id=76602 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
