Hi webkit-dev,

(and sorry for the duplicate post here, I mangled the headers on the
previous post!)

This is a request for WebKit's position on display-p3 support for Canvas
2D. This is already being tracked in bugs.webkit.org here


Adds a color space parameter to CanvasRenderingContext2DSettings, which
defaults to "srgb" and can take on the value of "display-p3".
Adds ImageDataSettings, which allows specifying a color space parameter to
getImageData/createImageData and related constructors.


WhatWG spec changes merged in this PR


Includes tests of ImageData (get and put), and ensuring no loss when doing
toBlob and toDataURL round-trips.

Thank you for your feedback!
