/*
  This file contains classes corresponding to window layouts
  defined in resources/mygui/ *.xml.

  Each class inherites GUI::Layout and loads the XML file, and
  provides some helper functions to manipulate the elements of the
  window.

  The windows are never created or destroyed (except at startup and
  shutdown), they are only hid. You can control visibility with
  setVisible().
