Detailed Description

Represents a point in space with an x and y integer or fixed point coordinate.

The default is integer math if nothing is specified. Serves two functions: 1. Allows easy intialization of fixed point like: point(3,4,FIXED_MATH); 2. Allows libraries that use point with fixed point to ensure that the point provided is a fixed point value where required.
