Bug #7239634 This change passes two matrices to the vertex shader instead of one. We used to compute the final MVP matrix on the CPU to minimize the number of operations in the vertex shaders. Shader compilers are however smart enough to perform this optimization for us. Since we need the MV matrix to properly compute gradients dithering, this change splits the MVP matrix into two. This has the advantage of removing one matrix multiplication per drawing operation on the CPU. The SGX 540 shader compiler produces the same number of instructions in both cases. There is no penalty hit with having two matrices instead of one. We also send so few vertices per frame that it does not matter very much. Change-Id: I17d47ac4772615418e0e1885b97493d31435a936
