  Up to release 1.3 of imlib2 there is a problem with the includes.
  Imlib2.h does not load Xlib.h.
  Workaround: add the following line:
#include <X11/Xlib.h>
#include <gdk/gdk.h>
#include <Imlib2.h>
#include <unistd.h>
#include <stdlib.h>
# include <X11/Xlib.h>
# include <X11/extensions/Xinerama.h>

  // [as] thinks that this is not portable enough
  // [lc]
  // I use a virtual screen of 1600x1200, and the resolution is 1024x768,
  // so I changed how screen_[x,y] is obtained; it seems that gtk 1.2
  // cannot give the geometry of viewport, so I borrowed from the source of
  // xvidtune the code for calling XF86VidModeGetModeLine, this requires
  // the linking option -lXxf86vm.
#include <X11/Xlib.h>
#include <X11/extensions/xf86vmode.h> // for XF86VidModeGetModeLine
