You're right -- at the time the size becomes available, the image never has any decoded frames, even if it needs to be decoded later to draw the page.  The code I added to catch this case doesn't actually work.

Would it be better to include the extra allocations in CachedImage's decodedSize?  Then the cache would clean up the data during a purge.
