Description:
Fix ugly output from make-parenthesis-stencil for increased thickness

issue 4532

This was caused by the fix for issue 3930. Small and very small
object were focused by 3930 and it did the job.
Though, obviously increasing the thickness for
make-bezier-sandwich-stencil
should have been limited.
