[mutter/wip/carlosg/input-thread: 111/157] backends: Move away from meta_cursor_renderer_get_position()

[Carlos Garnacho <carlosg src gnome org>]

commit 896d551b59658778b90f615c1453dddf3f093867

    backends: Move away from meta_cursor_renderer_get_position()
    
    We are moving onto relying fully on the seat cursor position. As
    this focuses (thus far?) on mouse pointers only, use the cursor
    tracker as a convenient shortcut.
