The cache manager could just keep track of possible cache hits before the shape is really cached. Say, if a certain character state was required about 3-5 times it will create a bitmap cache the fifth time and use that from that moment on. It has some downsides (memory usage, maybe not smooth playback in extreme cases) but would be a huge performance gain in some situations. Think of a complex background where a small sprite moves over. Normally the background would have to be rendered again and again even if it does not change. Caching the background would allow very fast movement of the simple sprite (starting from the fifth frame, when the cache is activated). I don't think Flash does something like this, but I often wished it would do so. Application-type flash movies would benefit from this method. :) However, this is just an idea, and it's already difficult enough to think about the renderer redesign. The "cache as bitmap" would just be a hint to the the cache manager, I see no problem there.
