I'm not arguing against that, I think we can provide sensible fallbacks
for all the cursors, eventually ending up with just the default cursor.

What I'm suggesting is a fallback strategy for the resizing cursors, along
with a suggestion for which ones should be marked as required.

That a cursor is marked as required doesn't mean we don't provide a
fallback for it, I see it mainly serving as a way of discouraging theme
authors from creating themes that create usability problems for the
end user.

Well I think there is a separation between the two, since in one case you'll
have a well defined name for the cursor, and in the other the name is
choosen by the theme author.

In the first case it's easy to share the aliases, but in the latter there's
a danger that we'll end up with conflicts if they're all installed in the
place. That artists don't choose the same names for the same bitmap
cursors is something I'm already seeing in existing themes.
