can you add info here on how they can use the allocator for bitmap reuse?

How does the new comment sound? Since bitmap reuse is fairly complicated, I'd
rather not put a full explanation of how to do it. On the other hand, I don't
want a caller to interpret the comment to mean that it's simple and do something
incorrectly.
