/*
 * QShell - placeholder for smaller windows (Form; Frame)
 * 28-04-1997: Created!
 * 21-02-1998: Stripped, since QWindows are now all XWindows
 * 09-08-1999: Now derived from QDraw (was QWindow)
 * FUTURE:
 * - EvExpose() should see if the damaged area hits the outline, and only
 *   repaint the border if needed.
 * (C) MarketGraph/RVG
