docs: // New creates a new window value from a window id and an XUtil type.
  // Geom is initialized to zero values. Use Window.Geometry to load it.
  // Note that the geometry is the size of this particular window and nothing
  // else. If you want the geometry of a client window including decorations,
  // please use Window.DecorGeometry.
