// Created:    Colin Day, July 2001
// Desc:       Window manager for the GUI edit tool, we want this up
//						 fast and to look like what we use in the game so we're going
//						 to use the WW3D window manager, and just override the
//						 drawing functions to draw lines and images to the
//						 display.  We will also be adding our own functionality
//						 here for editing and interacting with the GUI windows.
