Fwd: Why Ultra-Condensed, Normal and ultra-expanded have very small differences?

["Vitaly V. Ch" <vitaly v ch gmail com>]

Hi all!

I set font i following way:

   PangoFontDescription *pfd = pango_font_description_new();

   pango_font_description_set_family_static (pfd, "Courier");
   pango_font_description_set_size   (pfd, size);
   pango_font_description_set_weight (pfd,weight);
   pango_font_description_set_style  (pfd,PANGO_STYLE_NORMAL);
   pango_font_description_set_stretch(pfd, stretch);
   pango_layout_set_font_description (pl, pfd);

according my measuring differences between  Ultra-Condensed and
ultra-expanded is only 25% but I expect at least 200%.
