Add an example to exercise tessellation shader support
Also extended Renderer and friends to support setting the number
of vertices per patch with glPathParameteri(GL_PATCH_VERTICES, n).
To support this QMeshData now also stores the vertices per patch.
This demonstrates how to tessellate using quad tessellation mode.
Follow-up commits will add objects to show triangle and isoline
modes.
