Support --gravity.
2006-08-15 Behdad Esfahbod <behdad@gnome.org>
* examples/renderdemo.c (do_output), (parse_gravity),
(parse_options): Support --gravity.
* pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_scaled_font),
(compute_glyph_extents), (_pango_cairo_fc_font_new): Load rotated
scaled_fonts to handle gravity.
* pango/pangofc-fontmap.c (pango_fc_make_pattern),
(pango_fc_font_map_get_patterns), (pango_fc_font_map_load_fontset):
Set FC_VERTICAL_LAYOUT on West and East gravity.
