 M_SCALE Draws the map at a specified scale
         After M_GRID has been called, the map is sized to fit within
         the plot region of the current axes. If you want to force the
         map to appear at a specific scale (e.g. 1:250000), call

         M_SCALE(scale_factor)

         where the map scale is 1:scale_factor. The map will be drawn
         with its origin at bottom left within the figure limits (which
         can be set with calls to ORIENT or by setting the 'paperposition'
         property of the figure).

         M_SCALE('auto') returns to autoscaling.

         SC=M_SCALE returns the current scale (this is useful if you want to
         know roughly wht scale you currently have)

         see also M_PROJ, M_GRID.
