To help us iterate further, I've attempted to capture the essence of this
thread on the whatwg wiki, using the problem solving template.
I tried to capture the main ideas that we seem to agree on so far and I
started to think about how to handle special cases.

ImageBitmap is trying to just be a generic HTMLImageElement, that is, a
bitmap image. It's not trying to be anything more than that.
Based on some of these questions, though, maybe

flipping which pixel is the first pixel, for example, doesn't do

Nearly all GL games use non-premultipiled alpha textures. So all those
