/*
* vroot.h -- Virtual Root Window handling header file
*
* This header file redefines the X11 macros RootWindow and DefaultRootWindow,
* making them look for a virtual root window as provided by certain `virtual'
* window managers like swm and tvtwm. If none is found, the ordinary root
* window is returned, thus retaining backward compatibility with standard
* window managers.
* The function implementing the virtual root lookup remembers the result of
* its last invocation to avoid overhead in the case of repeated calls
* on the same display and screen arguments.
* The lookup code itself is taken from Tom LaStrange's ssetroot program.
*
* Most simple root window changing X programs can be converted to using
* virtual roots by just including
*
* #include <X11/vroot.h>
*
* after all the X11 header files. It has been tested on such popular
* X clients as xphoon, xfroot, xloadimage, and xaqua.
* It also works with the core clients xprop, xwininfo, xwd, and editres
* (and is necessary to get those clients working under tvtwm).
* It does NOT work with xsetroot; get the xsetroot replacement included in
* the tvtwm distribution instead.
*
* Andreas Stolcke <stolcke@ICSI.Berkeley.EDU>, 9/7/90
* - replaced all NULL's with properly cast 0's, 5/6/91
* - free children list (suggested by Mark Martin <mmm@cetia.fr>), 5/16/91
* - include X11/Xlib.h and support RootWindowOfScreen, too 9/17/91
