I try to introduce a per character rotation using lua.
But a negative rotation angle seems to introduce a vertical offset to
the base line.
It might be intended, but how to get it gone?
Any hints?

\def\streepA{%
\rotate[rotation=\ctxlua{context(math.random(1,15))}]{\|}%
}
\def\streepB{%
\rotate[rotation=\ctxlua{context(math.random(-15,-1))}]{\|}%
}
\def\stapA#1{\dorecurse{#1}{\streepA}}
\def\stapB#1{\dorecurse{#1}{\streepB}}

\startalignment[width]~
\dorecurse{50}{\stapA{10}\stapB{10}}
