// This helper function tries to set the input focus to the active (top level)

// Workaround a focus problem happening with GTK2 when running under Xvfb,
// i.e. keyboard and mouse events not delivered to the right window.
//
// Normally we would expect the input focus to be correctly set by the WM.
// But for some reasons, the input focus is set to PointerRoot under Xvfb,
// which means: all keyboard events are forewarded to whatever is underneath
// mouse pointer. and consequently, our fake events could be simply lost and
// do not reach the subject window at all.
