2000-04-04  Christopher James Lahey  <clahey@helixcode.com>

	* widgets/e-text/e-text-test.c: Got rid of some runtime errors.
	Changed to "fixed" font so that it will work on everyone's
	machine.  Added a white background rectangle.  Made resizing the
	window resize the contained text item.  Changed to using affines
	(e_canvas_item_move_absolute) instead of "x" and "y" attributes.
	Set the text in the entries so that they match the original values
	of the displayed text object.
