here is a small patch to fix two issues with cartoon meshes
(1) the vertices were not correctly ordered around the cartoon control points which did not look nice esp. for low hermiteLevel values.
(2) mesh triangles from opposing sides could cut through each other exposing the inside of the cartoon mesh
attached are before-after images for cartoon with hermiteLevel 1
I think this makes the lower hermiteLevel values much more usable and thus opens the hermiteLevel >0 display for larger structures and screen resolutions.
