Add CanvasRenderingContext2DSettings.pixelFormat to support higher bit depths
https://bugs.webkit.org/show_bug.cgi?id=283281
rdar://problem/140105324
Reviewed by Simon Fraser.
Start supporting different pixel formats in 2D canvas, as per
https://github.com/w3c/ColorWeb-CG/blob/main/canvas_float.md ,
with naming based on Chromium implementation.
This is needed to eventually support HDR.
This adds:
- An unstable preference "CanvasPixelFormatEnabled".
- CanvasRenderingContext2DSettings.pixelFormat of type CanvasPixelFormat,
which can be "uint8" (default) or "float16" for now.
(The property has no effects yet, but can be set and queried.)
