Detailed Description

Light-weight class that encodes a rotation by 0, 90, 180, or 270 degrees as well as optional horizontal and/or vertical flips.

In short, this convieniently encodes the eight ways in which a aligned rectangle can be linearly transformed to result in an aligned rectangle again. Especially useful for games with tile-based maps.
