 * TVision example: the classic life example

 * Written by Sergio Sigala <sergio@sigala.it>
 *
 * The mouse may be used to edit the patterns within the life window.
 * Clicking with the left button inside the life window will cause a dot to
 * appear at the cursor location.  Clicking with the right mouse button will
 * remove the dot.  This allows the user to create his/her own patterns.
