I'll assign this to me for the time being (on vacation for 2.5 more weeks though, so consider this up for grabs...)

I will also check it. :)

Oops, https://codereview.chromium.org/2248643003/

Yeah, that will fix this too - indirectly =)

Simplify time tracking in SMILTimeContainer

Instead of 5 difference time fields, use two - one to track the last
seek/pause time in the container ("presentation time"), and one to
track the document time corresponding to that.
Use two bool flags for tracking 'paused' and 'started' state.

Also straighten out code-flow in SMILTimeContainer::begin() to make it
a bit more obvious that we're essentially mirroring the contents of
updateAnimationsAndScheduleFrameIfNeeded. begin() is also renamed into
start(). Pass double to SMILTimeContainer::scheduleAnimationFrame, do
some ASSERT->DCHECK transformations when touching code and touch up
some comments.

Refactor SMILTimeContainer can-schedule-frame predicate

begin() and updateAnimationsAndScheduleFrameIfNeeded() use the same
predicate to check if they should schedule an animation frame - although
they phrase it slightly differently (because of local knowledge.)
Move the generic version to a canScheduleFrame() method and use that in
both cases.

Don't schedule a wake-up if the timeline hasn't started

Before the timeline has started we shouldn't update animations. This
makes resume() symmetric with pause().

Replace SMILTime with double for elapsed time in SMILTimeContainer

We don't really make use of of the special properties of SMILTime for
this case, and using double means slightly less impedance mismatching.
