               happened to change it. Let me emphasize-- in order to
               redraw array labels, we must call a function that redraws
               not only the _entire_ array and its graph, but also redraws
               the parent canvas in which the graph is displayed. There is
               no interface I can find to just say, "redraw the label".

               Worse, Pd redraws a single array at least 3 times, and maybe
               even the graph and the containing glist-- it's hard to tell
               because so much data is sent over the wire that I run out of
               buffer in my terminal window. These are a side-effect of
               garray_redraw, as well as the garray_resize branch above. (And 
               don't forget that the canvas dialog callback probably causes
               as many redraws as well.)

               Until the Pd codebase handles redrawing in a sane fashion,
               without depending on a vast array of side-effects, there's
               simply no way to effectively maintain it. */
