Ignore mouse enter/leave on non-exposed windows 

If you put two OpenGL widgets in two tabs, you will have several
QNSViews on the Mac (because using OpenGL forces a lot of the widgets
to be non-alien).  The GL widget on the non-visible tab will not be
exposed, but QCocoaWindow::childWindowAt is recursive and was returning
the last window found which contained the mouse location; but the
children are not reordered when switching tabs.  It should ignore
the invisible windows and report that the mouse entered the
one which is visible.
