* 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.
