Isn't there a way to remove all these modes and stuff by
0) always delegating allocator up to skia, e.g. instead of skia::DiscardableMemoryAllocator, use skia::MemoryAllocator
1) basically making the cache size a webkit preference that we set up in the embedder, and
2) making the lazy pixel ref have a mode saying "are you purged"? eg asume all lazy refs can be purged/lost then just deal with it? The thing is, other than the static cast here, and the size set differently, there's nothign much special webkit side about this...Isn't there a way to remove all these modes and stuff by
