Limit curve stroking threshold to reasonable range
Avoid unreasonable threshold values for extremely wide pens, since
that can lead to a very high processing cost.
The rare usecases where this would make a noticeable difference will
necessarily also be using scaling, and so is anyway depending on
setting a suitable curve threshold manually.
