Before this change, we used Gfx::Bitmap to represent both decoded images that are not going to be mutated and bitmaps corresponding to canvases that could be mutated. This change introduces a wrapper for bitmaps that are not going to be mutated, so the painter could do caching: texture caching in the case of GPU painter and potentially scaled bitmap caching in the case of CPU painter.
