new function, to generate postscript so i can test tree printing.

2000-06-14  Chris Toshok  <toshok@helixcode.com>

	* e-tree-example-1.c (print_tree): new function, to generate
	postscript so i can test tree printing.
	(create_tree): add print button.

	* e-cell-tree.c (ect_print_height): implement function (in a
	broken way for the time being, heh).
	(ect_print): implement function to draw tree controls and offset
	the subcell's printing.  icons aren't printed yet, just lines.
	(ect_draw): remove old unnecessary comments.  only draw the
	horizontal line in specific instances (well, add a test so a lone
	root node doesn't get the horizontal line.)
	(e_cell_tree_class_init): add print/print_height methods.
