Unless I am misreading this, there is still some confusion about printer
grafPorts.  The port is ALWAYS opened by the printer driver, and all
current Apple printer drivers initialize it to a black/white grafPort, not
a CGrafport.  This is true even if you pass in a pointer to a port that
you have allocated yourself; the reason you are allowed to pass a non-NIL
pointer is just so you can control the allocation of the space.  Hardly
anyone cares about this, so the pointer is usually a NIL.

If you open a color grafport and pass its pointer in when you call PrOpenDoc,
it just gets re-opened as a b/w grafPort (with current Apple drivers).
