The complete context is:
(require 'sawfish.wm.gnome.integration)
(setq customize-command-classes '(default viewport))
(setq viewport-dimensions '(3 . 2))

Would the equivalent of (defvar viewport-dimensions nil) therefore occur in
sawfish.wm.gnome.integration or customize-command-classes then?
That however implies that (define-special-variable viewport-dimensions..
would create a new local scope that is unconnected to the code to actually
do what is intended, or am I misinterpreting defvar as a variable 
definition and
storage allocation?

And could you combine (defvar foo nil) (setq foo bar) as (defvar foo bar)?
