Cherry-pick r284247. rdar://problem/84629726
REGRESSION (r276370): Elements with animated transform property might not properly rendered
https://bugs.webkit.org/show_bug.cgi?id=230753
Reviewed by Myles C. Maxfield.
Source/WebCore:
The change in r276370 was incorrect, resulting in the geometry map being used when
an element had a transform and `transform-style: preserves-3d`.
Fix by going back to testing for the presence of the various transform properties which
affect geometry. hasTransformRelatedProperty() is still useful as a fast bit-check.
Test: fast/repaint/transform-preserve-3d-repaint.html
* rendering/RenderGeometryMap.cpp:
(WebCore::canMapBetweenRenderersViaLayers):
LayoutTests:
* fast/repaint/transform-preserve-3d-repaint-expected.txt: Added.
* fast/repaint/transform-preserve-3d-repaint.html: Added.
