Revert "Revert "PixelRef now returns (nearly) everything that is currently in SkBitmap. The goal is to refactor bitmap later to remove redundancy, and more interestingly, remove the chance for a disconnect between the actual (pixelref) rowbytes and config, and the one claimed by the bitmap."""""" This reverts commit eabd6b2ed4e494b323c08f32358f45950a0368c3.
