	* gtk/gtkimage.c:
	Splitted gtk_image_clear into gtk_image_clear() and
	gtk_image_reset(). Call gtk_image_clear() in ::destroy
	to avoid leaks.

	* gtk/gtklabel.c (set_markup):
	Don't leak text.

	* gtk/gtktextlayout.c:
	Always free display->shaped_objects.

	* gtk/testgtk.c (create_clist):
	Don't leak custom style.
