 * This file takes care of the C implementation of opening up an

 *
 * also contains the use() and swap() functions for double buffering

 * Leo Chan  -- 1995

 * Adam King -- 1997
 *
 * Modified Creation window code to use the currently showing Java Frame
 * window instead of creating a new window.
 * ---------------
 *
 * Many improvements and changes are made !
