 *   Redraw the window frame.
 *
 * Input parameters:
 *   fwnd   - the framed window whose frame needs to be re-drawn.  This must
 *            have been previously created by nxtk_openwindow().
 *   bounds - Only draw the ports of the frame within this bounding box.
 *            (window relative coordinates).
 *
 * Returned value:
 *   OK on success; ERROR on failure with errno set appropriately
