test case

If a SVG font has no latin character, text which uses the font disappear. Text in the attached html should be displayed as "!いうえお".

SVGFontData::initializeFontData() doesn't initialize font metrics when the associated GlyphPage doesn't have glyphPageZero, which is supposed to store latin character mappings. This causes the problem.
