I'm not sure how we might implement that, because I know how to say "use
the default cursors (actually the parent's cursor - sometimes the root X
Window's cursor)", but not how to get the default cursor.

I suppose we could create the abstract concept of a default cursor
(implemented as a boolean) and check for it in each method that takes a
cursor. Is that what you mean?
