Note: It's tempting to just merge the new xcursor_init2 function into xcursor_init1 since they're very similar, but that's a bad idea. The xcursor_init1 function really is meant for init'ing an unused cursor; it's expected that immediately after, a full cursor-positioning action will occur. xcursor_init2 is meant for xcursors that have already been positioned, in which case their physical position is updated in order to keep their logical position unchanged.
