When a view hierarchy becomes VISIBLE, it is possible that the display
list of some of the subtrees needs to be recreated. In particular, if
the subtree was measured while it was GONE, then the children probably
didn't have a valid size. If a display list is created for any of the
subnodes in the tree during this time, then they may have clipped the
children out.
The fix is to force the parent to become INVALIDATED whenever a child
view's bounds change (and it is VISIBLE).
