Code review comment for lp:~afrantzis/mir/multimonitor-misc-fixes

90 + auto dp = position - output_rect.top_left;
91 + output.move_cursor({dp.dx.as_int(), dp.dy.as_int()});

I still prefer something like:

    auto change_of_origin = geom::Point{} - output_rect.top_left;
    output.move_cursor(position + change_of_origin);

But top-approving as no-one else cares.
