Thu May 27 15:32:03 2004  Owen Taylor  <otaylor@redhat.com>

        * pango/pango-font.h pango/fonts.c: Add underline and
        strikethrough position and thickness metrics.

        * pango/pangofc-font.c: Implement underline and strikethrough
        position and thickness metrics.

        * pango/pango-fontset.c (pango_fontset_real_get_metrics):
        Initialize metrics from the metrics of the first font
        in the fontset.
