Fix Viewport being visible after leaving tree

Browse source 
When a SubViewport leaves the tree, it is still displayed in its parent
SubViewportContainer until the next redraw.
This PR makes sure, that the parent gets redrawn immediately.

This also fixes the visibility problem when a SubViewport is added as
child of a SubViewportContainer.
