This is a sampling issue.  For the x-lines (scan lines) the setting
of "set samples" is used while for the y-lines the "set isosamples"
setting applies.  This can be useful for surface plots, where the
x-lines will be smooth and adjacent x-lines are linearly connected
a few times.  For pm3d this does not seem to be optimal.
