<h3>Log Message</h3>
<pre>Add a content-animation test with accelerated CSS animations
https://bugs.webkit.org/show_bug.cgi?id=161776
Reviewed by Dean Jackson.
PerformanceTests:
Add a test that measures the frame rate of accelerated CSS animations.
This is like css-animation.html (which animates 'left' and 'top') but animates
transforms instead. In order to get animation in X and Y we make two nested elements
and set transformX() on one, and transformY() on the other.
* Animation/css-accelerated-animation.html: Added.
Tools:
* Scripts/webkitpy/benchmark_runner/data/patches/ContentAnimation.patch:</pre>
