Reorganize plcolorbar code so the overall colorbar label is drawn with the separate static function draw_label.  This reorganization gives identical example 33 results to before and prepares the way to reposition the label to be centred relative to the bounding box of the inner decorated box and to also do bounding box calculations for the whole object (label + inner bounding box).
