It works for now, but we'll probably break it later.  For example, it
assumes that you are going from col 0 to col 1 to col 2.  If you get an
expose event in the last column, right now it's redrawing the entire
row.  However, we'd like it to only draw the effected column later -- in
which case you won't have the foreground set.

You should really just do:

cell=gtk_text_cell_new();
gtk_tree_view_column_new_with_attributes("col1",cell,"foreground", 0, "text" ,1, NULL);
gtk_tree_view_column_new_with_attributes("col2",cell,"foreground", 0, "text", 2, NULL);
gtk_tree_view_column_new_with_attributes("col3",cell,"foreground", 0, "text", 3, NULL);

etc.
