Bug 1955697 - Simplify scrolled canvas background painting. r=mstange ...
Always paint the scrolled canvas background if it's CSS-specified.
Compute the canvas background upfront so we don't need to walk the
display list after the fact.
This removes the scrolled canvas background in a few cases where the old
code could prove that it was not needed due to blending, see the
comment:
// To make layers work better, we want to avoid having a big non-scrolled
// color background behind a scrolled transparent background. Instead, we'll
// try to move the color background into the scrolled content by making
// nsDisplayCanvasBackground paint it.
It's unclear if that matters for performance with webrender nowadays,
but removing it does cause significant fuzzy failures, so it will be
reintroduced in a more explicit way in a follow-up patch.
