Yeah, time sorting of animations is quite unpleasant, but at least if
animateMotion and animateTransform are equals then even this unpleasantness
is consistent.

Implementation-wise (at least in WebKit) it's also much simpler to treat
animateMotion and animateTransform as instances of the same thing rather
than as two different concepts with different application rules.
