 * Customizable gradients.
   This belongs to gtkextra. The idea is that the user could define
   his own gradient level values and colors.

 * More Python and plugin support

 * 3D delaunay triangulation needs to be improved
   We are going to use a netlib routine in SG for fast Delaunay 
   triangulization. Another idea is to also support gts 
   (http://gts.sourceforge.net)

 * Interface for adding new file formats using Python
   We have to create a second type of plugins to add new file formats.

 * Memory consumption problems.
	- in sg_worksheet

 * Numerics and fittings.

 * i18n & internationalization improvements
	- translations in po/<lang>.po
	- src/sg_locale.[ch]: locale/gettext setup
	- *.[ch]: use of _(...) or gettext_noop(...) for translatable strings

 * documentation
 	- docs/*.[lyx,html,sgml]

 * A Lot more!
