Re: Canvas Floating Point Color Values Propoal

Thanks!

I've created a PR incorporating this feedback, and also fixing a couple of
inconsistencies at
https://github.com/w3c/ColorWeb-CG/pull/85

In particular, I was inconsistent about using "unorm8" versus
"uint8Clamped" for ImageData. I also changed ImageDataSettings to use
"dataType" instead of "colorType", since we are specifying the type for
ImageData's data member (BTW, would it better to use the full names of the
type "Uint8ClampedArray" and "Float32Array", rather than the abbreviated
"uint8Clamped" and "float32").

Let me know of any further feedback here or on the PR.
