------------------------------------------------------------------------------

1. AnimateImages - Fixed a problem when opening the image window with an empty
                   buffer list.
2. WidgetsPick - Fixed a problem with determining the coordinate ranges of
                 curvilinear lattices that have more than one data variable.
3. LatToGeomNaN - Modification to the "Range Cells" option to make its
                  function match its description in the help file.
4. DisplacePyr - Disallowed a 2-D lattice with 3-D coordinates as being the
                 displacement lattice.
5. DisplaceLat2 - Allowed the Function lattice to have more than one vector
                  component.
6. VectorMaker - Added ability to create a specific-sized reference vector.
                 Added normals to the triangles in the "Cross Arrows" and 
                 "Solid Cross Arrows" styles for more accurate shading.  Fixed
                 a problem whereby the data values from an input colormap were
                 not being used.
7. XYZ2 - New module.
