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.
