To specify the registration point of a vector shape's cast member, set the regPoint , centerRegPoint , or regPointVertex properties. By changing the location of the shape's registration point, you can modify the way certain kinds of animation look, such as rotation and vertex movement.

	Use the regPoint property to move the registration point to an arbitrary location. Setting this property changes the centerRegPoint property to FALSE .
	This Lingo places the registration point 20 pixels to the left and 31 pixels above the upper left corner of the shape's bounding rectangle:
	member(1).regPoint = point(-20, -31)
	Use the centerRegPoint property to move the registration point to the center of the shape's bounding rectangle. This yields the most predictable animations.
	member(1).centerRegPoint = TRUE
	When the centerRegPoint is set to TRUE , Director will always re-center the registration point whenever the shape is edited.
	Use the regPointVertex property to set the shape's registration point to one of its vertices. When the shape is rotated, for example, this will cause it to rotate around a vertex instead of its center.
	This Lingo sets the second vertex of the shape as the registration point:
	member(1).regpointVertex = 2
	The regPointVertex defaults to zero. When it is set to a nonzero value, the centerRegPoint property is set to FALSE and the regPoint property is set to the location of the specified vertex.
