Account for background drawable size changing when lrtb properties change

LayoutTransition may set the left, right, top, bottom properties of a View when
animating it. If the View has a background drawable, and if these properties change
the actual dimensions of the view, then the background drawable must be informed
of the size change in order to display itself correctly.
