tdf#108302: keep the font unrotated if @font isn't available.
We will create the font in ExTextOutRenderer for glyphs that are expected to be sideway in vertical writing, so we can reset the font escapement and orientation if @font ( windows notation of fonts for CJK vertical writing. ) isn't available. That will keep the font consistent with @fonts for those glyphs expected to be upright in vertical writing. Note that it is necessary to change text alignment of DC when such font is used.
