This change introduces a texture cache for immutable bitmaps in the GPU painter. The cache is persisted across page repaints, so now, on page scroll repaint, in many cases, we won't need to upload any new textures. Also, if the same image is painted more than once on a page, its texture will only be uploaded once. Generally, the GPU painter works much faster with this change on all pages that have images.
