Bug 77662 – [chromium] Add impl-thread support for fill-mode and direction css animation properties

• Component: WebKit Misc.
• Status: RESOLVED FIXED

There are css animation properties that aren’t yet supported by the cc-thread animation code. If we detect an unsupported feature, it is possible to return false in GraphicsLayer::addAnimation to revert to the usual, main-thread animation code, but we should support most/all css animation properties. Specifically: animation-direction, animation-delay, animation-timing-function, and animation-fill-mode.

This should not block turning the feature on by default, since we gracefully degrade.

I think "all" is a bit ambitious. Can you say specifically what this patch is adding support for?

> Source/WebKit/chromium/src/TextFieldDecoratorImpl.cpp:36
> +#include "Image.h"

this looks unrelated

> Source/WebKit/chromium/tests/CCActiveAnimationTest.cpp:72
> +TEST(CCActiveAnimationTest, TrimTimeAlternating)

is this sufficient test coverage?  should we have some tests for reverse as well?

It isn't. Added tests to cover reverse.
