Using surf with "LineStyle" option set to "none" does not draw anything (surface is hidden).
Bug Description
Using surf with "LineStyle" option set to "none" does not draw anything. The surface is hidden.
Steps to reproduce
Just use following modified example (coming from https://help.scilab.org/surf):
Z= [0.0001 0.0013 0.0053 -0.0299 -0.1809 -0.2465 -0.1100 -0.0168 -0.0008 -0.0000

surf(Z, "LineStyle", "none");
What is the expected correct behavior?
We should see the surface (only facets without the mesh).
Error log
No error but rendering is wrong.
