Maximal possible size of shapes displayed by the visualizer.
property MaxShapeSize: TRVStyleLength;
This value is measured in screen pixels or in twips (1/20 of point), depending on Units property of TRVStyle component.
If MaxShapeSize > 0, it specifies the the maximal possible diameter of an imaginary circle around each shape.
Unlike the most of other visualizers' "max size" properties, this property limits a size not of the whole diagram, but of its fragment (shapes).
If MaxShapeSize > 0, the maximal possible diagram size is:
(additionally, there is space around the diagram specified in Margin)
