RenderingLayerCustomViewport Property

When not null, then the specified Viewport is used to render RenderingItems in this RenderingLayout. By default, the X, Y, Width and Height values are specified in absolute units (without super-sampling). This can be changed by setting IsCustomViewportInRelativeValues to true. The MinDepth and MaxDepth are always in relative units (from 0 to 1).
