it seems that the anti-aliased renderer in FreeType has problems
rendering extremely thin straight lines correctly, at least when using
the FT_Outline_Render functions..
NOT-WINDOWS-METRICS
FreeType doesn't always return the same metrics as Windows for ascender,
descender and text height, depending on character pixel sizes. A lot of
testing on Windows is needed to debug this properly. It might be due to
a rounding bug when computing the "x_scale" and "y_scale" values.
