        * docs/Changes-1.4.txt: Started

	* gtk/Makefile.am (gdk_headers): Include all the new headers.

        * gdk/*.h gdk/*.c: Split gdk.h into lots of itty-bitty little pieces.

	* gdk/gdkprivate.h gdk/gdkcc.c: Moved GdkColorContext private
	into C file.

	* gdkinput.h gdkinputprivate.h - renamed the internal gdkinput
	header to gdkinputprivate.h.

	* gdk/gdk.h gdk/gdk.c: Removed gdk_time* functions which have been
	unused since before 1.2.
