Update ploticus to 1.41. Licence is now GPL.

Notable changes are:
 * Fixed bug: proc axis - when producing stubs running from negative
              to positive, zero is displayed as a very tiny non-zero
              value such as 5.2579e-17 due to rounding error.

 * Fixed bug: proc getdata - buffer overflow when 'filter' is used
              with data records longer than 254 chars, causing garbage
              result or instability.

 Version 1.41 as of 18 June '01:

 * Ploticus now covered under GPL.

 * Fixed bug: colored background not completely filling the result window
              when scale is being done

 * Fixed scripts in test suite: The change in default size (version 1.40)
   sometimes caused general layout problems with graphics that were layed
   out with an 8.5" x 11" default size in mind.  The solution for these
   scripts is to add a #proc page and specify pagesize: 8.5 11. Some of
   the scripts in the test suite had such problems and are now fixed.

 * Fixed bug: EPS bounding box incorrect for 1) pltab output and 2) pl
              where result draws into negative absolute coordinate space.

 * Fixed bug: proc areadef xautorange/yautorange not working correctly in
              some cases when a nearest= value is specified. This bug was
              apparently introduced in 1.40.

 * Fixed bug: proc lineplot - accum option choking when non-numeric data
              encountered.

 * Fixed bug: proc rangebar - negative barloc values not working.

 * Added: proc areadef - autorange datafield may now be a comma-delimited
          list of dfields so that multiple data fields are considered
          when determining the axis min and max.

 * Changed: scaletypes - times hh:mm:ss and mm:ss - validity checking
            relaxed slightly to allow degenerate values such as 0:4:9

 * Fixed bug: pltab - incorrect interaction between #font and
              sectionheadings

 * Fixed bug: proc rangebar - textdetails controls N= label but not
              missing label


 * Fixed bug: pltab - creates 8.5 x 11 inch gif, png regardless of result
              size

 * Fixed bug: axis - line grid and gridblock starting point incorrect in X

 * Fixed bug: axis - colors incorrect when specified in certain
              combinations for tics, stubs, grid

 * Fixed bug: bars - ticks not being drawn when truncating was not
              switched on

 Version 1.40 as of 16 Jan '01:

 * proc getdata - variables may be declared and set from within data files
                  using #set

 * proc curvefit - linear regression and correlation

 * proc areadef - "autowidth" and "autoheight" attributes for data-driven
                  plot area size

 * proc axis - alternating shaded block backgrounds

 * added: new script $functions - $exists() and $notexists() to test if a
          @VARIABLE has a value. See functions(pl)
          added: new script #operators - #hideund and #showund to control
          display of embedded underscores, and #includesh. See scripts(pl)

 * added: new scaletype - log+1 scaling for handling log-characeristic
          data that may contain values of 0.0

 * added: proc areadef - autorange - "incmult", which assists in
          automatically determining hi and low margin

 * added: proc areadef - "xextracategory" and "yextracategory" attributes,
          which allow categories to be added explicitly even when most
          categories are defined from data

 * added: proc axis - "stubcull" attribute for eliminating stub collision,
          or pile up on log axis

 * added: proc axis - definable extent for grid lines

 * added: cmyk color specification for use with PostScript and EPS.

 * added: textdetails - "font" subattribute for setting PostScript font.

 * added: proc print - "outfile" and "outmode" attributes allowing proc
          print to write to files

 * added: proc print - now sets a variable called NSELECTED.

 * added: proc legend - "reset" attribute.

 * added: proc bars - "hidezerobars" attribute

 * added: proc curvefit - "select" attribute

 * added: proc curvefit - new curvetype - "avg"

 * added: proc tabulate - "showrange" attribute supercedes
          showrangelowonly.  Range label can be the average of low and
          high end of range.

 * added: proc rangebar - "logmean" attribute, for computing means and
          standard deviations in log space.

 * added: proc rangebar - "statsonly" attribute, to compute stats and set
          variables without drawing the bar.
          added: proc rangebar - now sets the variables RANGEBARIQRMIN and
          RANGEBARIQRMAX.

 * changed: proc getdata - pl no longer quits when no data could be read.
            Scripts can check @NRECORDS after getdata finishes and take
            appropriate action.

 * changed: default result size is now 8" x 8".

 * changed: proc curvefit - data no longer need to be ordered on X for
            curve computation

 * changed: standalone $functions (those that are not part of an #if
            construct) may contain embedded white space

 * changed: color specifications - the separator character in rgb(r,g,b)
            constructs may be any of comma, dash, colon, or pipe. Comma
            was problematic if rgb constructs were put into a comma-
            delimited list, as in students example.

 * changed: .pls is now a "known extension" for script files.

 * changed: improved the heuristic for automatic axis increment
            determination

 * fixed bug: proc scatterplot - if select condition used or if values are
              out-of-range, labels from data and datapoint size from data
              may be incorrect due to data alignment bug.

 * fixed bug: proc lineplot - if select condition used or if values are
              out-of-range, labels from data may be incorrect due to data
              alignment bug.

 * fixed bug: proc rangebar - file close problem causing core dump on
              linux

 * fixed bug: multipage plots & page breaks - if proc page was used to
              break to page 2, and proc page wasn't used for page 1,
              drawing continues on page 1.

 * fixed bug: proc getdata - select was not working when field names used
              (message: no such data field).

 * fixed bug: date scaling - dates containing embedded dashes were not
              converted properly when used. as locvalue e.g. proc
              annotate location.

 * fixed bug: $max() function was giving incorrect results

 * fixed bug: proc page - on multipage landscape plots using PNG/GIF only
              the last page was viewable.

 * fixed bug: PNG/GIF driver memory leak when doing multipage plots.
              fixed bug: incorrect fda() calls in tabulate.c and
              processdata.c.

 * fixed bug: proc getdata filters - potential instability if references
              were made to data fields beyond NFIELDS.

 * fixed bug: proc bars - tics produced through the use of leftticfield,
              rightticfield, and midticfield were being drawn outside of
              plotting area
