Move PANGO_UNITS_ROUND here... ...from here.

2007-04-30  Behdad Esfahbod  <behdad@gnome.org>

        * pango/pango-types.h: Move PANGO_UNITS_ROUND here...
        * pango/pangofc-private.h: ...from here.

        * pango/pango-gravity.c: Document that pango_gravity_to_rotation()
        returns angle in radians but pango_matrix_rotate() takes degrees.

        * pango/pango-layout.c (pango_layout_run_get_extents):
        * pango/pango-renderer.c (pango_renderer_draw_layout_line):
        Retain metrics hinting when centering baseline (used for Latin, etc
        in vertical mode).

        * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_metrics),
        (pango_cairo_fc_font_glyph_extents_cache_init): Respect metrics
        hinting setting when moving glyphs around for vertical writing.

        * pango/pangocairo-fcfont.c (_pango_cairo_fc_font_new): Apply
        the gravity rotation before the pattern's matrix, such that
        vertical text gets correct italic direction.

        * pango/pangocairo-font.c (_pango_cairo_font_get_hex_box_info):
        Make hexbox font inherit most properties from the current font.
        That is, bold hexbox digits for a bold font, etc.
