David Rich uncovered a bug that triggered a core dump when printing
some documents.  The bug is tickled if these three conditions are met.

1. You are printing a document that contains an Idraw drawing that
   contains text.

2. You set the property '*idraw_font_metrics' to 'off'.

3. You have no PostScript font metrics files installed at your site.

This patch is archived as 'pub/3.0-fixes/fix8'.

============
    This patch assumes that fix6 has already been applied.
    Apply with ``patch -p -N < fix8'' at the top of the source tree.
