	* gtk/gtkbin.c (gtk_bin_add): better error message if you try to
	add a widget to a bin that already has a child.

	* gdk/gdkcc.h, gdk/gdkcc-x11.c: Remove GdkColorContext, #50512

	* docs/Changes-2.0.txt: note that GdkColorContext is gone.

	* gdk/x11/Makefile.am (libgdk_x11_la_SOURCES): remove gdkcc-x11.c

	* gdk/gdk.h: remove gdkcc.h

	* gdk/Makefile.am (gdk_public_h_sources): remove gdkcc.h

	* gtk/gtkpixmap.c (build_insensitive_pixmap): rewrite using
	GdkPixbuf, since the previous implementation was GdkColorContext
	dependent.

	* gtk/testgtk.c (create_pixmap): add test for insensitive GtkPixmap
