That is, it should support surfaces that it doesn't waste time clearing in deallocate(), because the consumer of said surface knows that it's going to paint over the whole thing.

This may not make sense for the other applications, but it would shave ~3.7% of completely unnecessary main thread time off of my remote layer painting stress test.
