fix ghost clipBounds problem

OverlayViewGroup clipChildren=true, so that RenderNode
of GhostView will be forced clip its content to its bounds.
Because GhostView is transformed to a different location
other than (0,0),  the content left/up to the bounds
is clipped out.

Introduce another clipChildren=false view between
OverlayViewGroup and GhostView.
