Clip the contained text.

2000-06-13  Christopher James Lahey  <clahey@helixcode.com>

	* e-cell-text.c: Clip the contained text.

	* e-table-group-container.c: Did a first pass at grouped
	printing.  This works, but there's no fancy boxes or headers
	around the groups.

	* e-table-item.c: Added will_fit function and added quantize
	function to _height.
