MS Windows style should use pango_win32_font_description_from_logfont;

2008-09-18  Dominic Lachowicz  <domlachowicz@gmail.com>

        * modules/engins/ms-windows/*: MS Windows style should use pango_win32_font_description_from_logfont;
        Allows us to rip out a lot of potentially buggy code, and also get the font specification from the
        XP theme (#434987)
