	* gtk/gtkcolorsel.c (gtk_color_selection_class_init): do not call
	gtk_settings_get_default() here as that requires an X connection
	(which breaks doc building with no X connection) and is not
	multihead safe
	(gtk_color_selection_init): delay palette loading until realize
	time
	(gtk_color_selection_realize): load the palette, and initialize
	the global palette if it hasn't been already

	* gtk/gtkpreview.c (gtk_preview_class_init): don't initialize the
	visual/cmap fields of klass->info since they are gone
	(gtk_preview_get_visual): just return gdk_rgb_get_visual ()
	(gtk_preview_get_cmap): just return gdk_rgb_get_colormap ()
	(gtk_preview_realize): don't set VISUAL and COLORMAP attributes

	* gtk/gtkpreview.h (struct _GtkPreviewInfo): remove visual and
	cmap fields
	(gtk_preview_get_visual):
	(gtk_preview_get_cmap): mark as deprecated

	* docs/Changes-2.0.txt: add a little note about the GtkPreviewInfo
