Code review comment for lp:~mir-team/mir/cursor-spike-phase-1-resubmit

The use of arbitrary cursor_name strings eliminates the need for any theme right now, even in the game case. Because your game can just:
    load_cursor("my_special_menu_cursor");

I'd rather not take the approach of land it now and fix it later. It's not clear any theme specification will be required at all in the foreseeable future. And it just creates design disagreements over what a theme represents.
