Add a special size for drag-and-drop GTK_ICON_SIZE_DND (Default to 32x32)

Browse Source 
Sun Jun 24 21:34:32 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkenums.h gtk/gtkiconfactory.c: Add a special size for
	drag-and-drop GTK_ICON_SIZE_DND (Default to 32x32)

	* gtk/gtkdnd.c (gtk_drag_dest_set_target_list): Fix problem
	with un'reffing wrong list reported by Jeff Franks.

	* gtk/gtkdnd.[ch] (_gtk_drag_{source,}dest_handle_event): _prefix.

	* gtk/gtkdnd.c (gtk_drag_set_icon_default): Use GTK_STOCK_DND
	for the default icon. Remove inline XPM.

	* gtk/gtkstock.h gtk/gtkiconfactory.c:
	Add GTK_STOCK_DND GTK_STOCK_DND_MULTIPLE (Currently, stock_new
	is used for GTK_STOCK_DND, but it is a bit too small.)

	* gtk/stock-icons/stock_dnd_multiple.png
	gtk/stock-icons/Makefile.am: New stock icon moved from gnome-libs.

	* gtk/gtkdnd.c (gtk_drag_source_event_cb): Only return
	TRUE when starting a drag. In other cases, we are
	just observing. (#52995)

	* gtk/gtkdnd.[ch] (gtk_drag_set_icon_{stock,pixbuf}): Add
	function to set the icon for a drag from a GdkPixbuf
	or stock ID.

	* gtk/gtkdnd.[ch] (gtk_drag_source_set_icon_{stock,pixbuf}):
	Likewise, for drag sources.

	* gtk/gtkdnd.h: Deprecate gtk_drag_set_default_icon.
	(Now should be done using the stock system.)
