Gets or sets a fixed bounding rectangle to be returned by
ComputeDiagramBounds.
public Rect FixedBounds {get; set;}
Property Value
By default this has Double.NaN values, meaning that
ComputeDiagramBounds should actually compute the union of all of the parts in the diagram. If all X/Y/Width/Height values are actual numbers, this value is returned by
ComputeDiagramBounds.
