Fri Oct 1 18:03:36 1999 Owen Taylor <otaylor@redhat.com> * 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.
