I'm not sure I like this in the WebCore namespace. Do we need it in more than one place? i.e. can it be file static?

It seems it is only used in GPUSwapChainMetal, so I think it can live there for the moment.

Ugh. I wonder if WebGPU should use better names here. Or maybe those are the names everyone expects?

I might make the small changes and land this patch.

OK! Metal seems to make them a little nicer, in that R8G8B8A8 -> RGBA8, but I guess it doesn't matter.
