Optimize gatherTransparentRegions to account for transparent bg gatherTransparentRegions() incorrectly takes the background into account even when that background drawable is a completely transparent ColorDrawable (which you can get by calling View.setBackgroundColor(0)).

Issue #13465427 Performance suggestion: View.setBackgroundColor(0) should set background to null Change-Id: Ic552bf6a07cc9229fd32febc3ada73a0701cad0c
