Detailed Description

Describe a rectangular area with coordinates expressed in pixels.

The rectangle is represented in terms of its top/left and right/bottom borders.

In some cases, rectangles are assumed to obey to the following invariants:

xmin <= xmax ymin <= ymax

Oddly, the xmin and ymin coordinates are inclusive, while the xmax and ymax coordinates are non-inclusive. This design decision makes several computations simpler and lets you specify empty (0x0) rectangles without breaking the invariants.

Computing the size of a rectangle can be done by simply subtracting the maximum X or Y coordinate from the minimum X or Y coordinate.
