Helper class for FLIP animations. FLIP is an approach to animations that
takes remaps animating expensive properties, like width, height, left and top
to significantly cheaper changes using transforms. It does this by taking two
snapshots, one of the element's First position (F), another of its Last
position (L). It then uses a transform to Invert (I) the element's changes,
such that the element appears to still be in the First position. Lastly it
Plays (P) the animation forward by removing the transformations applied in
the Invert step.
