FlattenEncoder -> ByteEncoder -> PostscriptEncoder -> PostscriptEncoderToDisk, and the Postscript Encoders are used by the Postscript Canvas.     ByteEncoder is in  "MorphicExtras-Postscript Filters", so if you nuke that entire category, you would appear to also nuke Postscript support.

D'oh! Yes of course you are right. I overlooked that PrintableEncoder
has subclasses. Thank you.

So there may be some unreferenced classes and methods, but "MorphicExtras-Postscript Filters"
definitely is required.

I really don't know. Maybe someone else can answer?

Thanks,
