/*
** This routine adds information to the input texts that doesn't change
** when the display is resized or when new fonts are selected, etc.
** Mostly this means adding style attributes.  But other constant
** information (such as numbering on <li> and images used for <IMG>)
** is also obtained.  The key is that this routine is only called
** once, where the sizer and layout routines can be called many times.
**
** This routine is called whenever the list of elements grows.  The
** style stack is stored as part of the HTML widget so that we can
** always continue where we left off the last time.
**
** In addition to adding style, this routine will invoke callbacks
** needed to acquire information about a markup.  The htmlPtr->zIsVisitied
** callback is called for each <a> and the htmlPtr->zGetImage is called
** for each <IMG> or for each <LI> that has a SRC= field.
**
** This routine may invoke a callback procedure which could delete
** the HTML widget.
**
** When a markup is inserted or deleted from the token list, the
** style routine must be completely rerun from the beginning.  So
** what we said above, that this routine is only run once, is not
** strictly true.
