XGL with more/less than 4 workspaces

[Alexandre Franke]

One question just came to my mind. What would happen with XGL if I had
not 4 but say 3 or 5 workspaces? I mean, default gnome/KDE settings is
4. All the videos I have seen show XGL having 4 workspaces, which
implies that they are on the four sides of a cube (top and bottom
faces don't count because they are blank, which will lead to the
second question, see below). So how would or does XLG behave if I have
another number of workspaces (if this is possible)?

Second question: top and bottom faces are blank on all the videos I
have seen, except one where there's an Impress presentation (this one
was about 10 minutes long and shows many features, David Reverman's
and Novell's names appear at the beginning).
Do these faces serve any purpose? How can they get used?
