"Unfortunately I don't have any access to Windows 98 or Macs with <OSX, or
any font editors except FontForge, which presumably does not use any
Windows libraries at all.  Does anyone on this mailing list have one of
these?"

I tried the font in Visual TrueType versions 4.2.1 using the black and
white and grayscale modes, and I saw the artifacts you noted in your
initial screenshot. I can't tell exactly what version of the Win rasterizer
is being used in VTT, as it's all under the hood.

thanks
