Detailed Description
A straight sided DICe::Shape made of an arbitrary number of sides.
NOTE: Coordinates are always in image coordinates, i.e. (0,0) is the upper left corner, x+ points to the right, y+ points down
NOTE: Vertices must be listed in order as the boundary of the polygon is traversed (clockwise or couterclockwise), otherwise the polygon will have folds.
Constructor & Destructor Documentation

Constructor that takes the vertices as arguements.
- Parameters
-
