// We aim to match IE here.// -IE uses a font based on the encoding as the default font for form controls.// -Gecko uses MS Shell Dlg (actually calls GetStockObject(DEFAULT_GUI_FONT),// which returns MS Shell Dlg)// -Safari uses Lucida Grande.//// FIXME: The only case where we know we don't match IE is for ANSI encodings.// IE uses MS Shell Dlg there, which we render incorrectly at certain pixel// sizes (e.g. 15px). So, for now we just use Arial.const String& RenderThemeChromiumSkia::defaultGUIFont(){    DEFINE_STATIC_LOCAL(String, fontFace, ("Arial"));    return fontFace;}
