I'm not sure. Can you provide the info in About Squeak for these two, and
which OS you're running on?

If I look at the size of the generated code for all revisions of the
VectorEnginePlugin I don't see any obvious changes that would account for
this.

$ for c in `git log src/plugins/VectorEnginePlugin/VectorEnginePlugin.c |
grep \^commit | sed 's/^commit //'`; do echo $c; git show -s --format=%cd
$c;git show $c:src/plugins/VectorEnginePlugin/VectorEnginePlugin.c | wc;
done

Hmmm, the current commit contains primStrokeWidthHop, not primStrokeWidth.
So this changed in April of last year:

Looks like it. I would check the Cuis vectorEngine sources and see if they
have changed,
