Safari 14 on 2x display renders NYS DMV page as blurry
https://bugs.webkit.org/show_bug.cgi?id=220528
<rdar://problem/71440246>
Reviewed by Tim Horton.
Source/WebCore:
Certain combinations of nested perspective and transform cause Core Animation to
rasterize at unit scale, which makes layers blurry on Retina displays.
Enable code that was already used on iOS to set layer rasterization scale.
Test: compositing/contents-scale/hidpi-tests/rasterization-scale.html
* platform/graphics/ca/cocoa/PlatformCALayerCocoa.mm:
(WebCore::PlatformCALayerCocoa::setContentsScale):
LayoutTests:
* compositing/contents-scale/hidpi-tests/rasterization-scale-expected.html: Added.
* compositing/contents-scale/hidpi-tests/rasterization-scale.html: Added.
