OK, I think I understand whats going on - an ImageView displays the
image by: view.setBackground(imageyouwanttosee);
this is not want I would want or expect, for precisely the reason that
my clipping does not affect it. its lazy in my opinion. If I want to
display a view with an image as a background, then I will call
setbackground ON ANY TYPE OF VIEW. thats not what ImageView
specifically should do in my opinion - it should set the image in the
foreground so that view operations can be done on it.
Im calling 'bug' on this.
