        Part of Bug 332266 – gdk_draw_layout fails for coordinates >= 2^21

        * pango/pango-types.h:
        * pango/pango-matrix.c: New public API:
                pango_matrix_transform_distance()
                pango_matrix_transform_point()
                pango_matrix_transform_rectangle()
                pango_matrix_transform_pixel_rectangle()

        * pango/pango-utils.h:
        * pango/pango-utils.c: New public API:
                pango_units_from_double()
                pango_units_to_double()
                pango_extents_to_pixels()

        * pango/pango-layout.c (pango_layout_get_pixel_extents),
        (pango_layout_line_get_pixel_extents): Use pango_extents_to_pixels().

        * pango/pangocairo-fcfont.c:
        (pango_cairo_fc_font_glyph_extents_cache_init),
        (compute_glyph_extents): Use pango_units_from_double().

        * examples/renderdemo.c (do_output): Use
        pango_matrix_transform_pixel_rectangle();

        * pango/pango.def:
        * docs/pango-sections.txt:
        * docs/tmpl/glyphs.sgml: Update.
