 * Project: Simple Windowing Interface Manager (SWIM)
 *
 * Description:
 *  This package provides a simple windows manager that provides the
 *  following functions:
 *     Windows initialization and validity checks
 *        Must be in physical display space
 *     Color support for background, primary pen, and fill
 *     Simple graphics primatives (pixels, lines, boxes)
 *     Window deallocation
 * 
 *  A maximum number of windows, defined by WINDOWSMAX can be created.
 *  A window can be reclaimed after it has been initialized.
