Animator should also support implicit animations.

[itssidhere]

I am using an animated container to transform the position of the widget. Animated Container only requires one X and one Y point to do a transformation from one coordinate to another but I can't find any way to do that with the animator as I can't get the old X and Y.

The new Widget AnimateWidge supports implicit animation. see #56 and #57
