We do this by projecting each polygon of the Polyset onto a 2-d plane,
then running a tessellation algorithm on the projected polygon. Then we
project the generated 2d triangles back up into 3d space.
project each of the newly generated 2d 'tiles' (the polygons used for
tessellation, typically triangles) back up into 3d space.
(in reality as of writing, we dont need to do a back-projection from 2d->3d
because the algorithm we are using doesn't create any new points, and we can
