Bug 1223658 - Part 4: Add a function to check active duration is zero. r=birtles,dholbert We are going to pass animations to the compositor in before phase but not to pass when active duration is zero. To distinguish this state we need a new function to check that the active duration is zero. MozReview-Commit-ID: 2Lckmt4LQcV

Bug 1223658 - Part 3: Consider fillMode in compositor thread as well. r=birtles We need to consider fill mode in compositor thread as well as other properties because pulling the animation back from the compositor thread is sometimes delayed due to the main thread busyness. In such situations, if there is another animation running on the main thread on the same element, users can easily notice a gap between both of animations. MozReview-Commit-ID: 1i7YTWboira

Bug 1223658 - Part 2: Pass delay property to compositor. r=birtles The check of negative elapsedDuration is basically no longer valid since animation delay is not factored into start time any more. But still we have somtimes met negative elapsedDuration sice we use a previous vsync time stamp for async animations to make the animations more sync. This is not a problem in most cases but makes two reftests intermitent failure because both of them used steps(1, start), the steps(1, start) composed different results in the before phase and in the active phase. To avoid this difference this patch replace the steps(1, start) with steps(1, end). Once we incorpolate playbackRate into GetCurrentOrPendingStartTime, we don't need to call AnimationTimeToTimeStamp for deviding delay by playbackRate since the time passed to AnimationTimeToTimeStamp does not contain delay any more.

Bug 1308317 - Part 8: Just use an nsTAutoArray. r=froydnj This switches over from using a half-baked auto array to nsTAutoArray. MozReview-Commit-ID: 6FR2SjOhoZR

Bug 1308317 - Part 7: Remove nsSupportsArray::RemoveElementsAt. r=froydnj MozReview-Commit-ID: H3A3gxckw5o

Bug 1308317 - Part 6: Remove nsSupportsArray::GetIndexOfStartingAt. r=froydnj This removes the scriptable method |GetIndexOfStartingAt| which is unused in our codebase and turns up no references in the plugins repo. This allows to remove the non-scriptable |IndexOfStartingAt| which is folded into |IndexOf|. MozReview-Commit-ID: 2ADz5mLIvMU

Bug 1308317 - Part 5: Remove nsSupportsArray::DeleteLastElement. r=froydnj |DeleteLastElement| is scriptable, but a search of our add-on repo turned up no hits and there were no references in gecko code. This also allows us to remove the non-scriptable |RemoveLastElement| which was only called by |DeleteLastElement|. MozReview-Commit-ID: 20FXBrosacA

Bug 1308317 - Part 4: Remove nsSupportsArray::Equals. r=froydnj |Equals| is not scriptable and unused in our codebase. MozReview-Commit-ID: BsbJIuR9fSk
