/* FvwmTaskBar Module for Fvwm.

 * (Much reworked version of FvwmWinList)
 *  Copyright 1994,  Mike Finger (mfinger@mermaid.micro.umn.edu or
 *                               Mike_Finger@atk.com)
 *
 * Two little hacks by DYB: 1) make size of a strip in hidden state tunable
 * (with *FvwmTaskBar: AutoHide <pixels>); 2) make process of TaskBar
 * hiding/unhiding more smooth.
 *
 * Minor hack by TKP to enable autohide to work with pages (leaves 2 pixels
 * visible so that the 1 pixel panframes don't get in the way)
 *
 * Merciless hack by RBW for the Great Style Flag Rewrite - 04/20/1999.
 * Now the GSFR is used and there are no other flags (olicha may 19, 2000).
