Fixed 17833 and 17866. Most of these files fix 17833, which enables opt-in behavior of reversing a transition in place, rather than the current snap-to-end behavior, via the new Effect property "autoReverse". Also, FxRotate changes fix 17866, where it was not taking into account any constraints or position set on the object, so that transitions with just an FxRotate would not properly reset any constraints to their from-state values.
