// MAINTENANCE_TODO: Refactor this to separate per-aspect data for multi-aspect formats. In particular:
// - bytesPerBlock only makes sense on a per-aspect basis. But this table can't express that.
// So we put depth24unorm-stencil8 and depth32float-stencil8 to be unsized formats for now.

The only thing left right now is bytesPerBlock, which is a huge pain to refactor, but was also always the biggest problem, so it still needs to get fixed. But I'm not going to do it right now I think.

The last PR fixes one test using bytesPerBlock; it may be helpful for figuring out how to fix other things.
