You’re right that it shouldn’t be necessary for the toolbar to be created and
redrawn for every redisplay. This patch is a big improvement on the previous
situation, but it is incorrect, in that the various ENABLED-P elements in the
toolbar buttons are ignored. What we should do is pay attention to whether any
of the the toolbar buttons are dirty, and only then redraw.
