Indicates the "straightness" of the curves that connect points.
This property is used only when CurveType
property is CURVE_STANDARD. Valid values are between 0.0 and 1.0,
where 0.0 indicates straight lines, and 1.0 indicates lines with the highest

To create a curve region, first build an ordered array of points for the curve. Then create the region based on the array. The CurveSize property specifies the size of the array. Either specify a large array to start with, or increase the size of the array as needed, without losing existing points. For each point, update the following indexed properties:
and define the characteristics of the curve by setting the following properties:
