Subject: implement printing (pixbuf_print_height): implement print height

2002-04-24  JP Rosevear  <jpr@ximian.com>

	* e-cell-pixbuf.c (pixbuf_print): implement printing
	(pixbuf_print_height): implement print height
	(e_cell_pixbuf_class_init): set printing virtual methods

	* e-cell-toggle.c (etog_print): remove clipping, default clipping
	is done by the table, scale based on toggle height

	* e-table-item.c (e_table_item_calculate_print_widths): make the
	scale 1:1
