2000-09-06  Jody Goldberg <jgoldberg@home.com>

	* color-group.c (color_group_new_named) : strdup the name if it is
	  supplied by the user.
	(color_group_class_init) : Use the destroy method.

2000-09-03 Michael Levy  <mlevy@genoscope.cns.fr>

	* color-group.c : Re-write of color-combo-group.c to allow
	for arbitrary widgets to share a common color history.

	* widget-color-combo.c :
	Extracted all the code required to make the color table and moved it to a
	new object (ColorPalette). Changed the ColorCombo so that it uses
	the ColorPalette (and the shared color hsitory provided by the groupped
	ColorPalettes).
	All the code that refered to the creation of the color table was
	removed, and when appropriate, moved to color-palette.c
	Removed all mention of ColorComboGroups (as these no longer exist).

	* color-palette.c : Extracted from widget-color-combo.c
	(color_palette_new) : Creates a color palette.
	(color_palette_get_current_color) : returns the current color.

	* color-combo-group.c : New GtkObject meant to group color combo boxes so
	that their custom color histories are shared.

	well as those required size, and navigate through the custom color history.

	combo box's custom color history with the one stored in the group

	it to group_new_custom_color. Also added call to
	color_combo_group_add_color in order to notify group of change
	(color_combo_new_with_vals) : Added mandatory group name to
	function prototype. Also added call to color_combo_group_new_named
	and connected the "new_custom_color" signal emitted by the newly
	created group to group_new_custom_color
