It should also work as written above.  Each call to plwind() sets up a
PLWindow that contains relative device coordinates & world coordinates for
that window, up to a maximum of PL_MAXWINDOWS (64) per page per stream.  Is it
possible that you've exceeded 64 plots?  In that case it wraps around.
The current implementation was a quick hack & should probably be replaced
with something dynamically (re)allocated.
