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):

   -0.0014   -0.0017    0.3189    2.7414    7.1622    7.1361    3.1242    0.6633    0.0674    0.0030];

surf(Z, "LineStyle", "none"); 

What is the expected correct behavior?

We should see the surface (only facets without the mesh).
