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.

To respond on the topic of WebGL/ImageBitmap integration - and in
particular some of the features requested earlier in the thread. Apologies
if I missed a post where this stuff was already addressed directly; I
couldn't follow this thread easily because of how much context was stripped

Thanks Ken, that makes it much clearer to me.
The main concern I have with all this is the potential for OOM crashes.
I'm happy as long as the spec remains vague about what "undue latency"
means, so we still have the possibility of gracefully degrading performance
in low memory conditions by evic

I don't think that's true. The options only make sense for WebGL --
flipping which pixel is the first pixel, for example, doesn't do

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

In order for ImageBitmap to be useful for WebGL we need more options
Specifically
premultipliedAlpha: true/false (default true)
Nearly all GL games use non-premultipiled alpha textures. So all those
games people want to port to WebGL will require non-premultipied textures.
Often in games the alph
