That code could be made to work again. Some investigation is required, 
though.

However I'm strongly about that. This points to a real problem we need 
to address. The lineage Smalltalk-76 -> Smalltalk-80 -> Squeak -> Cuis 
comprises almost 50 years. A lot of code has been written! Some things 
have been made obsolete by much better options. This is one of them. 
VectorGraphics offers way more flexibility and unbelievable better 
quality graphics.

We need to classify packages in, perhaps, these categories:
1 - Abandoned.
2 - Maintained, but only for historical value. Use beyond that is not 
recommended.
3 - Somewhat maintained. Bitrot possible, and usually fixed in no more 
than a couple of months. If bugs are reported, someone fixes them in no 
more than a few weeks.
4 - Maintained. Someone or several people act as maintainers. They 
regularly use it and problems are detected and fixed quickly. If a bug 
is reported, it is acknowledged in no more that a few days, and fixed in 
no more than a week or two.

The Pen package would be in category 1, unless someone volunteers to 
maintain (and fix!) it. In any case, it would never go beyond 2, unless 
someone rewrites it to use Vector Graphics.


These categories for asses
