Function _finalizeElementPosition

docs/app/js/sanddance-app.js:31978–31988

* Finalizes the element positon based on the hostElement. Only returns the * rectangle values to position such that they are anchored to the target. * This helps prevent resizing from looking very strange. * For instance, if the target edge is top and aligned with the left side then * the bottom

(elementRectangle, hostElement, targetEdge, bounds, alignmentEdge, coverTarget, doNotFinalizeReturnEdge)

 * For instance, if the target edge is top and aligned with the left side then
 * the bottom and left values are returned so as the callou shrinks it shrinks towards that corner.

// Since the beak is rotated 45 degrees the actual height/width is the length of the diagonal.
