This file defines three classes that are used in the graphics
library to encapsulate basic geometrical concepts:
GPoint - A point containing an x and y value
GRectangle - A rectangle with x, y, width, height
GPolygon - A vector of GPoints marking the vertices of a polygon
| Classes |
| GPoint | This class represents a point on the real-valued graphics plane. |
| GRectangle | This class represents a rectangle on the graphics plane and is conventionally used to denote the bounding box for an object. |
| GPolygon | This class represents a polygon and consists of a vector of the vertices. |
