This has been partially fixed by 2e91648bcba06832dfa92bd742c32b2f5c1ad989.
No check is done about the real output, but all dash patterns have a period at
least as long as the tolerance (tanking the ctm into account).
The true output might still be all zeroes in some degenerate cases (for example
many sub-output-precision dashes summing up to a dash pattern with a period
greater than tolerance), but it should be very infrequent as long as output
precision in higher than tolerance and/or patterns are not composed of a lot of
dashes.
