What kind of tests do you have in mind? More specifically do you mean simply adding tests that expand on the existing
`doTestSnapshotScaleNodeDefer`and `doTestSnapshotScaleNodeImm` (which basically just prove that taking a snapshot
returns a non-null image of the expected size)? Or do you think we need to include a test that proves the snapshot
produced by tiling is entirely faithful to the original, pixel-wise?
