The only call site is RenderLayerBacking::getCurrentTransform().

Comment on attachment 397682 [details] Patch This is testable. Please also add an assertion in renderer().animation() or renamed to legacyAnimation().

^ testable like compositing/visible-rect/animated.html with non-default transform origin and an origin-sensitive transform like a rotate.

This code was added in r251252, the fix to bug 201892.

I'm renaming the accessor to legacyAnimation() in bug 211082.

Not sure if we actually need to call animatedStyleForRenderer() here at all, I believe we can't end up in the `if (applyOrigin == RenderStyle::ExcludeTransformOrigin)` code branch with a running `transform` animation since it would be accelerated and thus we'd return earlier on in `RenderLayer::currentTransform()`.

I tried to modify the provided test to set a negative delay for the animation to be half-way through but the output is still the same with or without the patch.

It should if you dump visible rects and/or tiling.

The webAnimationsCSSIntegrationEnabled flag no longer exists, but this may yet still occur.
