To make this work, we tag their pixelrefs as temporarily immutable, allowing ourselves to restore the pixels to mutability only when the image drops away. This should allow us to wobble back and forth between writing to the Surface and reading from the Image without a COW, with the Surface seeing mutable pixels and the Image seeing immutable pixels. The big idea is, Image doesn't need forever-immutable pixels, it just needs pixels that are immutable as long as it's alive.
