// views being affected by setting the parents' setClipChildren to false.
// The problem in Android is that a ViewGroup either clips ALL of its children or it does not. Unlike iOS, the clipping
// cannot be controlled on a per view basis. So clipToBounds=false will have to be somehow achieved with stacking different
// views on top of one another in an AbsoluteLayout or GridLayout. There is always a workaround when playing with layouts.
