	* gdk/gdkcolor.c (gdk_colormap_get_system): Only query
	  the colormap for GRAYSCALE and PSEUDOCOLOR visuals,
	  and don't ask for more than 256 colors in any case.

	* gdk/gdkwindow.c (gdk_window_internal_destroy): Remove
	  the input window information when we destroy the window,
	  not when we are notified of it.

	* gdk/gdkinputcommon.h (gdk_input_device_new): Work around
	  bug in XFree86 3.3.1's handling of Wacom macro buttons.
	  by assumming no device will report exactly 25 buttons.

	* gdk/gdkinputcommon.h (gdk_input_common_other_event): Fill
	  in string translation for generated key press events,
	  do sanity checking on received key codes.

	* gdk/gdkcc.c (gdk_color_context_new): Allocate enough
	  room for a GdkColorContextPrivate, not just for a
	  GdkColorContext.
