Postscript printing is supported. Any morph can be saved to Postscript or
EPS file for printing. I don't know much about this topic, but the classes
supporting Postscript output are in category 'MorphicExtras-Postscript Canvases',
and they don't appear to have any connection with the encoder classes in
'MorphicExtras-Postscript Filters'.

Are there any external packages outside of the Squeak image itself that
make use of these encoders and expect them to be in the image?

Thanks!
Dave
