That would feel like a step back in cleanups.
When an X11-independent part is split out from libXcursor, maybe it
could grow an API for saying "look for <insert-name-here> theme
configs", and the X11 part would hardcode the current behaviour.
Btw. it seems not all cursor sets have all cursor images, so we'd need
a fallback. Maybe this one fallback cursor could be distributed with
Weston and would replace all cursors in case there is no cursor theme
found at all. Or maybe it should be distributed with the Xcursor non-X11

other cursor fixes commits after that, since I don't want to be
