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.
