Don't set the PC_EXPLICIT flag for unused palette entries, that might have

	* gdk/win32/gdkcolor-win32.c (free_colors): Don't set the
	PC_EXPLICIT flag for unused palette entries, that might have
	undesired side effects. Just set them to black. Black is always
	present in a palette, so having superfluous black entries won't
	cause any extra allocations from the system palette either when
	realized.

	* gdk/win32/gdkevents-win32.c
	(gdk_event_translate:WM_QUERYNEWPALETTE): Don't do anything if the
	system visual is static color, i.e. the user has told GDK to use
	just the 16 static colors. In that case no need to redraw
	anything, as the colors are static and by definition always
	correctly mapped in the system palette.
	(WM_PALETTECHANGED): Ditto, no need to call UpdateColors() either.
