Convenience function that inserts a new column into the GtkTreeView
with the given cell renderer and a GtkCellDataFunc to set cell renderer
attributes (normally using data from the model). See also
gtk_tree_view_column_set_cell_data_func(), gtk_tree_view_column_pack_start().
If tree_view has "fixed_height" mode enabled, then the new column will have its
"sizing" property set to be GTK_TREE_VIEW_COLUMN_FIXED.
