Sure.  There's (screen-width) and (screen-height), which give you the
dimensions of the viewport.  Then (head-offset (pointer-head)) and
(head-dimensions (pointer-head)) will give you the offset and dimensions
of the head with the pointer -- so run those twice each, once for each
head.

I'm pretty sure that if I'm right about the first bit I'm right here.
Unless it's possible to have one head in one viewport and the other in
some other viewport?  But the viewport code would have to support that,
and there's nothing in there for that. Besides, I can't think of any
reason for it to be done that way.
