Andrej and Wolfgang,

Please, take care with the draw pakage. I have commited a new version of
it and some options were removed/changed or created. New features
need Gnuplot 4.2 installed:


* Graphic options function_style, fill_style
  and label_color were removed.
* Option line_type redefined; possible 
  values are now 'dots' and 'solid'.
* Image-style rendering of matrices (gray
  and rgb).
* New options:
  - filled_func: for explicit 2d functions.
  - color: by name or by hexadecimal cromatic
    components; no more integer indices needed.
    This color is used in lines, polygon borders
    and labels.
  - palette: palette specification for images.
  - colorbox: adds/removes the color box in
    pm3d mode.
  - fill_color: for polygons and explicit 2d
    functions.
  - eps_width & eps_height: dimensions (cm)
    for Postscript terminals.
  - enhanced3d: sets pm3d mode in Gnuplot.

The documentation in texi format is in
http://maxima.cvs.sourceforge.net/maxima/maxima/doc/info/draw.texi

More examples added to

Sorry for not having announced these changes in the list before, but the
package is still in its infancy.

Best wishes.
