Bug 1305325 - Part 6: Send animations even if it's paused, finished or zero playback rate. r?birtles. If all of animations on an element are paused, finished or zero playback rate, we don't send those animations to the compositor. MozReview-Commit-ID: CHjv6Buy5fa

Bug 1305325 - Part 4: Update base values for each property. r? This patch adds a hashtable to store the non-animated base value of each property animated by the effects in EffectSet. The values are stored as StyleAnimationValue objects since they are intended to be used in KeyframeEffectReadOnly::ComposeStyle. 1) We have to update it even if there is no animation properties changes because changing non-animating style value does not cause any animation property changes. If we do it in Updateproperties() it's apparently less effective. 2) There is the case that we have no EffectSet in UpdateProperties(), e.g. creating an animation. What happens on Element.animate(); i) KeyframeEffect constructor i-1) UpdateProperties() ii) Animation constructor with the effect ii-1) KeyframeEffectReadOnly::SetAnimation() ii-2) The effect is added in EffectSet MozReview-Commit-ID: FPzyX9fxxx3

Bug 1305325 - Part 3: Add AnimValuesStyleRule::GetValue and HasValue to get the last composed style. r?birtles HasValue() will be used to check that we have already composed style for a given property or not. MozReview-Commit-ID: L8lezGyON5o

Bug 1305325 - Part 2: Add AnimationProperty::HasNonReplaceComposite. r?birtles We will resolve base values only if HasNonReplaceComposite() returns true. MozReview-Commit-ID: LUui9BpuphW

Bug 1305325 - Part 1: Move test cases in file_partial_keyframes.html into file_disable_animations_api_core.html. r?boris Missing keyframe will be handled only if the Web Animatins API is enabled. Test cases in file_partial_keyframes.html will not throw any exceptions once we handle missing keyframe because they are run with the Animations API pref, but still we should run the test cases with disabled the pref. So we are now going to move the test cases into file_disable_animations_api_code.html. We can't use KeyframeEffectReadOnly contructor in a new test file since the constructor is also behind the Web Animations API pref. MozReview-Commit-ID: 9ApVxJebBUj
