Merge r228796 - [GTK] whatsapp web blurry in some parts, sharp on others
https://bugs.webkit.org/show_bug.cgi?id=182673
Reviewed by Carlos Garcia Campos.
CoordinatedGraphicsLayer::createBackingStore() uses the scale factor returned by effectiveContentsScale(),
which is always 1 if selfOrAncestorHaveNonAffineTransforms() returns true. But this fuction always returns
true if the layer has an AnimatedPropertyTransform animation, which means that layers with those animations
won't use the appropriate scale factor, causing blurry renderings.
This patch removes the animations check, so animated layers properly use the required scale factor.
No new tests, no behavior change.
