+/* Gtk has an annoying habit of 'overresizing'; superfluous resize
+   events within panels that cause all hell to break loose for a
+   while, only to have the panel finally look exactly like it did when
+   it started.  This happens especially with expander widgets.  There
+   are two problems: One, it's ugly as Hell to click an expander and
+   have the whole window freak out just to make a little space.
+   Second, having the Plot resize will trigger a recompute, which
+   could seriously screw the user.
+
+   The below lets us freeze/unfreeze an auto-resizing box's
+   child at its current size without queueing resize events. */
