Reviewed by Simon Fraser.
Make sure we use RenderLayer::currentTransform() when querying the target's
transform to ensure that it accounts
for accelerated animations. Indeed, RenderLayer::transform() will only account
for the transform set on the
`RenderStyle` which does *not* update during the course of an accelerated
property animation.
