Pie resize correctly updates transformed wedge paths

pie.js
* Fixed bug in resize() that resulted in regenerateTransformedWedgePaths
  being called prior to the resize animation completed and the paths
  were correctl updated for each wedge.  This issue resulted in
  mouse pass-through breaking after a resize operation.

Additional notes
* It was discovered that if stop() is called on a Raphael element,
  the animate() callback isn't executed.  In the case of animateJQP,
  the repercussion of this is that the promise isn't resolved.  For
  that reason, until a fix is provided, animateJQP should not be
  used in conjunction with stop().
* Split changes from "-0 issue" back into grid.js.
