Message:

Added VisibleOnScreen? property to all ui controls. This is a read-only
property that tells you if the object is actually visible or not,
taking into account visibility of parent objects and sizers.

Fixed a problem in the getter of dSizerMixin.Visible: querying it when
it hadn't been explicitly set would result in an AttributeError?.
