[Mesa-dev] [PATCH] Add GPU BLIT of texture image to PBO in Intel driver

Add Intel driver hook for glGetTexImage to accelerate the case of reading texture image into a PBO. This case gets huge performance gains by using GPU BLIT directly to PBO rather than GPU BLIT to temporary texture followed by memcpy. No regressions on Piglit tests with Intel driver. ---
