This one derives from e-cell-toggle.

1999-11-30  Miguel de Icaza  <miguel@gnu.org>

	* e-cell-checkbox.c (e_cell_checkbox_new): This one derives from
	e-cell-toggle.

	* check-emtpy.xpm, check-filled.xpm: new files.

	* e-cell-toggle.c (etog_draw): Paint in white.
	If we have transparency enabled, do the nice alpha computation.

	* test-table.c, test-cols.c: new files;  They implement the split
	tests.
