Subject: Rewrite to reduce the number of strcmps.

Sun Feb 24 13:40:55 2002  Owen Taylor  <otaylor@redhat.com>

        * pango/pangoxft-fontmap.c (pango_xft_pattern_equal):
        Rewrite to reduce the number of strcmps.

        * pango/pangoxft-fontmap.c (pango_xft_font_map_load_font):
        Compute the patterns as for load_fontset(), then just
        return the first. This takes advantage of our caching
        strategy.
