Yeah, true... I guess the problem that you and other are hitting is
that you're using the 'core' them, that is, the cursors built-in to
the X server.  libXcursor special cases those and there are no cursor
files on disk that we can load for the weston clients.

Right, we only parse that in the desktop-shell client.  I don't know
then, maybe we should go back to shipping a cursor theme with weston
that we can fall back on if loading fails.
