gtk/gdk/x11/gdkwindow-x11.c
Owen Taylor e9b6bfcc01 Move all X specific code into the x11/ directory. Aside from shuffling 
Mon Nov  8 14:47:04 1999  Owen Taylor  <otaylor@redhat.com>

	Move all X specific code into the x11/ directory.
	Aside from shuffling things around, did the following:

       * gdk/gdkprivate.h gdk/gdk.h gdk/x11/gdkmain-x11.h: Add
	 gdk_arg_context_* - a simple argument parsing system
	 in the style of popt.

       * gdk/gdkdrawable.[ch] gdk/gdkprivate.h gdk/gdkwindow.[ch]
	 gdk/x11/gdkprivate-x11.h:
	 Remove X specific stuff from GdkDrawable and GdkWindowPrivate -
	 add ->klass and ->klass_data fields. The klass_data
	 field points to an auxilliary structure that is
	 windowing system dependent.

       * gdk/gdkfont.c: Make most of the measurement functions
	 simply wrappers around gdk_text_extents().

       * gdk/gdkfont.c gdk/gdkprivate.h gdk/x11/gdkfont-x11.c: Add a
	 _gdk_font_strlen() function that hides the weird
	 behavior in gtk+-1.[02] where a string is interpreted
	 differently for 8-bit and 16-bit fonts.

       * gdk/gdkevents.c: Add a new function gdk_event_button_generate()
	 to store common code for synthesizing double/triple
	 press events.

       * gdk/gdkgc.[ch]: Virtualize in the same way as gdkdrawable.h.
	 Make all the function that modify an existing GC
	 simply wrappers around gdk_gc_set_values().

       * gdk/gdkcc.[ch]: Moved into x11/ directory in preparation
	 for throwing out later.

       * gdk/gdkfont.c gdk/gdkimage.c gdk/gdkcolor.c: Change GdkFontPrivate,
	 GdkImagePrivate and GdkColormapPrivate to have a
	 windowing system dependent part (GdkFontPrivateX etc.)
	 that "derives" from the system-independent part.

       * configure.in gdk/x11/Makefile.in gdk/x11/gdkinput*.c:
	 Got rid of the included-source-files for XInput in
	 favor of automake conditionals. (Which didn't exist
	 when XInput support was originally added.)

       * gdk/gdkrgb.c: Remove the visual id from the debugging
	 statements since that is X11 specific; print out
	 type/depth info instead.
