       any array field templates that our gtemplate will depend on. If we find
       a match we will refuse to create the gtemplate. However,
       template_cancreate starts from the struct name for a template that
       already exists.  On the first time through this recursive function,
       there isn't a containing structname yet. So we suppress this conditional
       the first time through the recursive loop, and then set the structname
       for all subsequent iterations through the loop.

   We recurse all the way to the end of the glist (and, for the
   groups, as deep as they go) and then call the functions from the bottom up.
   This way the clicks can "bubble" up from the bottom.  This has the effect
   that the shape visually closest to the front gets called first.

   This is called "event bubbling" in the HTML5 DOM.  You can also call
   events in top down order in HTML5/SVG as well (called "capturing" or
   "trickling"). But because some old version of Internet Explorer only did
   bubbling, that is the most widely used model today, and the only one
   I decided to implement here.

   However, [group] doesn't yet have an outlet to report events. Only a
   single [draw] should report a click here atm.
