RoundedPolygon class final

The RoundedPolygon class allows simple construction of polygonal shapes with optional rounding at the vertices. Polygons can be constructed with either the number of vertices desired or an ordered list of vertices.

This constructor takes the number of vertices in the resulting polygon. These vertices are positioned on a virtual circle around a given center with each vertex positioned radius distance from that center, equally spaced (with equal angles between them). If no radius is supplied, the shape will be created with a default radius of 1, resulting in a shape whose vertices lie on a unit circle, with width/height of 2. That default polygon will probably need to be rescaled using transformed into the appropriate size for the UI in which it will be drawn.
