indentSideFactor property
A number ranging from 0 to 1.0 defining how much indentation on the sides to produce the inner corner of the star. A value of 0 means inner corner is at center. A value of 1 means inner corner is closer to the outer side and makes the star look more like a circle. Default is 0.5 (half-way between center and outer edge)
