In <3880@bwdls58.UUCP>, hwt@.bnr.ca (Henry Troup) asks "How can anyone
design low level hints without  knowing if the the device is
write-white or write-black?"

I just want to point out that, according to my documentation, several
of the TrueType operators include a "distance type for engine
characteristic compensation". This is a code which indicates whether
the distance value associated with that operation is "black", "white"
or "grey", but the actual details of how to compensate for this are
left to the implementation.

See, TrueType isn't *that* low level after all...
