[Gmsh] Version 3

[Alessandro Vicini]

I just downloaded latest version and had a quick look at it. First of all, thank you to all developers as the new version is really a big step forward.
I have one question: I see that if I generate a sphere using its primitive function, and then I export the unrolled geometry, I find splines (and thus lots of points) inside it, instead of simple circle arcs. Is there some specific reason for this? Is it related to the use of the opencascade kernel?
