2002-10-02  Werner LEMBERG  <wl@gnu.org>

	Redesigning color support in troff.  Colors are no longer
	represented as separate nodes but are now part of glyph nodes and
	friends.  This fixes the current formatting misbehaviour due to the
	changes introduced on 2002-09-20.  Some extra code is necessary for
	proper grotty support: Without adding color variables to
	space-related nodes, the background color would be changed too late.
