// 1. The start offset of our 2D region is a multiple of 64 lines
// 2. We use the whole pitch.
// If these conditions are not met, we need to upload the entire tile (or at least the affected tiles wholly)
// FIXME: There is a 3rd condition - write onto already-persisted range. e.g One transfer copies half the image then the other half is copied later.
// We don't need to load again for the second copy in that scenario.
