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.

Doc: Updated content for Drill Down example

QtWidgets/Drill Down example uses images and information about Nokia's
old office locations as content. This change updates the example to
use concepts related to Qt instead.

In addition,
    - Documentation, screenshot updated accordingly
    - Corrected aspect ratio when scaling image items in the scene
    - Added a gray background with a slight gradient
    - Removed Symbian-specific code remnant

Fixed crash associated with reparenting a QGLWidget

We need to make sure that we don't reset() the context when the
QGLWidget is being reparented, as that will lead to the QOpenGLContext
being destroyed and not recreated, leading to a crash in makeCurrent().

Also, don't destroy() the widget if it has not yet been created, as in
that case there's no ParentAboutToChange event sent.
