Details:

For graphics toolkits qt/fltk when printing a contourf plot to a file
(pdf/png), the file will show the lines of the patches of the underlying
surface fill/triangulation.


close all;
clear;

graphics_toolkit qt
[xx yy zz]=peaks();
contourf(xx,yy,zz);
colormap summer

print contourf.pdf


Result is attached. Unfortunately I have no possibility for testing with the
current dev version.

gnuplot toolkit does not show this issue.

W.F.
