[mutter/wip/carlosg/input-thread: 53/96] backends: Add ::device property to MetaCursorRenderer




commit ac76cca8522e8fbfa4725eda3554206df62fc9f1
Author: Carlos Garnacho <carlosg gnome org>

    backends: Add ::device property to MetaCursorRenderer
    
    A cursor renderer is made to invariably follow a pointer device, make
    it a construct-time property, and update all creators of cursor renderers
    to specify it.
