Owen Taylor cc223eeff6 Fix stupid error introduced last night that was making things decidedly
Sun Jun 24 11:29:35 2001  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkimage-x11.c (gdk_image_new): Fix stupid error
	introduced last night that was making things decidedly not work.

	* gtk/*.[ch]: Patch from Kristian Rietveld adding 80 getters
	so that we have getter/setter pairing everywhere it makes
	sense. (#55767)

	* gtk/gtkradiobutton.[ch] gtk/gtktoolbar.c tests/testgtk.:
	Rename gtk_radio_button_group to gtk_radio_button_get_group, add a
	deprecated compat macro. (#55516)

	* gtk/gtklabel.[ch]: Add functions
	gtk_label_set/get_use_underline(), gtk_label_set/get_use_markup(),
	gtk_label_set_label(), which mirror the property API for GtkLabel.
	Make gtk_label_get_attributes() only reflect the attributes
	set by gtk_label_set_attributes.

	* gtk/gtknotebook.c (gtk_notebook_set_current_page) gtk/gtkcompat.h: Rename
	from gtk_notebook_set_page().
