/**

*
* \section intro Introduction
*
* Asciiquarium is a KDE screensaver to draw an ASCII art aquarium. This is the
* documentation of the API used in the program to generate the effect. It should
* be fairly simple, but basically:
*
* class AASaver is the main class, which handles outside events. All of the
* processing happens in the Screen class however, which manages a list of
* Sprites, updating them and drawing them as needed. When AASaver receives a
* paintEvent(), it forwards it on to Screen to handle it.
*
* Each Sprite is composed of 1 or more Frames. When a Screen wants a Sprite
* to draw itself, the Sprite forwards the request to its currently shown Frame.
*
* The Frame is rectangular, and created from textual ASCII art, with a ASCII
* art shape and color mask. The mask is optional. See aasaver.cpp for
* examples for creating a Frame.
*
* The Frame supports transparency and colors, and will convert the textual data
* into a TQPixmap representation on demand in order to reduce CPU load (at the
* expense of a slight memory usage increase for each sprite).
*
* Screen handles the timing for the project, and at each timeout will call
* Sprite::tickUpdate() from Screen::doAnimate().
*
* This whole program was inspired/copied from Kirk Baucom's asciiquarium
* program, from http://www.robobunny.com/projects/asciiquarium/
