mesa: add common format-independent memcpy-based ReadPixels path
I'll need the _mesa_readpixels_needs_slow_path function for the blit-based version, but it's also useful to have this memcpy-based path in one place and not scattered across several functions. v2: add "const" to function parameters Reviewed-by: Brian Paul <[email protected]> Tested-by: Brian Paul <[email protected]>
