Title: Fix for issue #197: don’t update bitmap when the view has not been measured yet

This fixes issue #197.
When I applied the solution from #228, it still didn't position the showcase view properly (pointing at 0,0) since it was now being called immediately, when nothing is drawn on the screen.
This solution saves the target for later evaluation in onGlobalLayout when the hierarchy is drawn.
