Issue description

CSGSphere3D on the left and a mesh instance SphereMesh on the right. They both are configured with 5 rings but the CSGSphere3D produces a mesh with 4 rings instead. The result is always rings-1.

Steps to reproduce

• Add a CSGSphere3D. Set rings to 5.
• Add MeshInstance3D. Set rings to 5.
• Enable display wireframe.

This would be a matter of definition, the documentation just states "Number of horizontal slices for the sphere.", which it has! It has five sections, but only four horizontal dividers, the description for SphereMesh is "Number of segments along the height of the sphere." which could be interpreted differently
