extract a slice from a tetrahedron

• generates the rendering commands for a sliced tetrahedron
• 2 cases: slice geometry consists of either 1 or 2 triangles

Parameters

v0	is the first of four corners of a tetrahedron
v1	is the second of four corners of a tetrahedron
v2	is the third of four corners of a tetrahedron
v3	is the fourth of four corners of a tetrahedron
o	is a point on the slicing plane
n	is the normal of the slicing plane
