Detailed Description

template<class T>
class Geom::Rectangle< T >

Basic 2D rectangle class.

This class is a bit more complicated than would be expected at first sight. This is caused by the problem of coordinate system sign. For example, in user interfaces, top is a lower number than bottom. But for normal coordinates, this is (of course) not the case. Still, also for floating point types, reverse axes are common.
