	* pango/pangowin32-fontmap.c
	(pango_win32_font_description_from_logfont)
	(pango_win32_font_description_from_logfontw):
	Map words that indicate weight and slant in the font name into the
	corresponding Pango font description settings, and strip those
	words from the family name. This maps for instance the DejaVu
	Sans, DejaVu Sans Condensed and DejaVu Sans Light fonts into a
	single DejaVu Sans family with styles Ultra-Light, Condensed,
	Oblique Condensed, Oblique, Bold Condensed, Bold, Bold Oblique
	Condensed, and Bold Oblique, which is nice.
