Don't need this check because getResourceClass is only called by X11Client and Unmanaged.

opacity() is overridden in Deleted so this check can be dropped.

Ideally, Toplevel::opacity() should be implemented as follows

  double Toplevel::opacity() const
  {
      return m_opacity;
  }

getWmOpaqueRegion() is only called by X11Client and Unmanaged so this check can be dropped.

pid() must be overridden by Deleted.

windowRole() is overridden by Deleted.
