Detailed Description

A sprite is a free roaming texture that is directed using Signals and Slots.

A Sprite is a self managing visual object that can be directed to move in various ways at a rate lower than the frame rate of the application. It will continue to move until it has carried out the last instruction, or a new instruction is received.
