20.1.5.2 backdrop (Backdrop Plane)
This element defines a plane in which effects, such as glow and shadow, are applied in relation to the shape they are being applied to. The points and vectors contained within the backdrop define a plane in 3D space.
[Example: Consider the following image as an explanation of the backdrop plane definition:
.gif "DocumentFormat.OpenXml.Drawing.Backdrop-image001")
In this image we see a plane being defined by an anchor point, the vector normal to the face of the plane and a vector pointing up in relation to the plane. end example]
