REGRESSION(r268615): some accelerated transform tests are failing
https://bugs.webkit.org/show_bug.cgi?id=217851
<rdar://problem/70394402>
Reviewed by Dean Jackson.
Source/WebCore:
When we added support for accelerated individual transform properties animations, we added
the notion of base transform animations which are used to set the base value of any
transform-related property that is not animated.
Those animations were defined to start as early as possible, assuming that a very small value
after 0s was as early as possible. However, it's possible that other animations start with a
negative time if they have a delay or are seeked, if the value returned by CACurrentMediaTime()
is smaller than that delay. This means that if the machine had been booted for less time than
an accelerated animation's delay, the base transform animation wouldn't overlap.
We now ensure that those base transform animations start as early as the earliest animation
that is being committed in a call to GraphicsLayerCA::updateAnimations().
