bugfix: naming points in drawings

We had a regression since commit 60e1023f0 on Nov 27. Turns out we do
need the ancient hack after all.

But no, we won't go back to the hack. It's a simple problem to fix
right. And while we're at it, we'll fix the test harness to be more
realistic so it would have caught this problem.
