Not essential, but it seems you'll need to implement image() isFixedSize() fixedSize() isPending() and knownToBeOpaque() anyway, so maybe you should do that now with stubs?

Nit: .

Should you return nullptr if there are arguments for now? I guess not.

Drive-by, but I think this needs to be escaped as an identifier. I'm ~sure this would yield wrong results for stuff like paint(foo\ bar).
