Owen Taylor 6341c2f9a2 Make the default default colormap the GdkRGB colormap, not the system 
Fri Sep  7 18:50:59 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_widget_get_default_colormap):
	Make the default default colormap the GdkRGB colormap,
	not the system colormap.

	* gtk/gtkinvisible.c (gtk_invisible_init)
	  gtk/gtkwindow.c (gtk_window_init): Set the current
	colormap, as returned by _gtk_widget_peek_colormap()
	on the widget.

	* gtk/gtkwidget.[ch]: Export _gtk_widget_peek_colormap
	to GTK+. Make it return %NULL instead of the default
	colormap if no colormap has explicitely been pushed.

	* gtk/gtkwidget.c (gtk_widget_get_colormap): Check for
	colormaps on ancestral widgets before defaulting the
	the system default colormap.

	* docs/Changes-2.0.txt: explain colormap changes.
