This reverts commit 11422c63d3.
Reason for revert: Perf regression
Original change's description:
> Tie mip map cache purging to Images, not Bitmaps/PixelRefs
>
> We were potentially using different keys for lookup vs. add, because we
> were adding with a key based on the pixelRef, which may not have the
> same uniqueID as the originating image.
>
