REVISION SUMMARY
  Some platforms support to hide and show the cursor. This will be needed
  by e.g. the zoom effect which currently only provides this functionality
  on X11.
  
  This change introduces a new method in the Platform to hide and show the
  cursor. The methods need to be called balanced and the implementation
  takes care of only showing again if all hide got matched by a show.
  
  The actual hiding and showing is performed in the platform plugins. So
  far the DRM and X11/Standalone platforms implement the required
  functionality, though other platforms probably could implement as well.
