#757 – RenderSize, ActualHeight and ActualWidth

The ActualHeight and ActualWidth properties of an element that inherits from FrameworkElement indicate the final height and width of the element, after layout has taken place.

This same information is also available via the UIElement.RenderSize property (UIElement is the parent class of FrameworkElement).  RenderSize is of type Size, which is a struct containing the width and the height.
