Detailed Description

The DRect class defines a rectangle in the plane using integer precision.

class DRect provides the following operations:

DRect == rect	Comparison operator Returns true if the rectangle is equal to rect else false
DRect != rect	Returns true if the rectangle is different from rect else false
