Draw overall label relative to the bounding box of the rest of the decorated (including tick marks, numerical labels for ticks, exponents, and end caps) colorbar.  This change greatly simplifies the draw_box arguments and logic, and makes a much nicer-looking result.
Draw overall label relative to the bounding box of the rest of the
decorated (including tick marks, numerical labels for ticks,
exponents, and end caps) colorbar.  This change greatly simplifies
the draw_box arguments and logic, and makes a much nicer-looking
result.

ToDo: Calculate complete bounding box of label + rest of the decorated
colorbar.
