I think you are right.

For page 6 of the normal sombrero function (which is what triggered this
report initially) some of the upper surface contours do look broken even
under tk zoom.  But I find entering coordinate ranges by hand a really bad
interface to zoom in on a trouble spot so I didn't pursue it perhaps to as
high a magnification as I should have.

I abandoned that approach and tried gv on the corresponding psc file. At
ordinary magnification the upper surface contours look broken, but if you
use either anti-aliasing or higher magnification without antialiasing they
look okay.

Since the psc device gives good results, I conclude there is nothing wrong
with the contour drawing in the plsurf3d core.

Sorry for the "wild goose chase", but apparently you found and fixed anothe=
r
bug so at least it wasn't a waste of time.

As far as I am concerned your beautiful new features are ready for release.
Thanks very much for this effort.  Will you please do the honors on the
PROBLEMS and NEWS files?
