This appears to be a truncation error due to the formating string we
use to represent floats in backend_ps. Darren, should we prefer 1.3e
instead of 1.3f, or perhaps 1.4e or 1.5e?

John, Darren,
I would suggest something like 1.5g, which will be less bulky for common cases than 1.5f.
Matlab ps files have all paths already transformed to paper coordinates but in very small units (thousandths of an inch?) so that they can be given as integers.

Replacing %f by %e and %1.3f by %1.5e in the latest svn version's backend_ps.py solves the problem.
cheers,

Random number generation is the art of producing pure gibberish as quickly as possible.
I think 1.4g is the way to go. It's fixed in svn 2252.
