In www.freetype.org www.freetype.org , FT_GASP_SYMMETRIC_SMOOTHING If set,
smoothing along multiple axes must be used with ClearType. This is entirely
incorrect. From the observed behaviour of Microsoft ClearType renderers, the
behaviour is as following: If set, 6×5 or 6×1 oversampling may be used. If
unset, 6×1 oversampling is always used. This in turn roughly translates to
FreeType language to the following: If set, smoothing along multiple axes may
or may not be used with ClearType. If unset, smoothing along multiple axes
should not be used with ClearType. The sentence "If set, smoothing along
multiple axes must be used with ClearType." is therefore incorrect and
should be changed.
