Eric, Ben,

See if the section "What is interactive mode" makes sense to you.  I 
have just added it to a feature branch (which includes some other faq 
madifications, mainly moving the backend section from installation to 
usage), but have not yet generated a pull request.  It doesn't go into 
every detail, or into the underlying machinery.  It is intended to 
provide just enough understanding to clear up user-level confusion about 
interactive mode, show, and draw, and let most relatively new users get 
on with their work.
