	Would be more expensive... but also more safe.
	Maybe the "inside" test could be simplified... For instance, instead
of counting the odd/even number of triangles that the test-ray hits, why
not to test the surface normal of the FIRST intersected triangle ? I'm
not sure, but I guess the dot product of the ray and this normal will be
positive if inside the mesh, negative if not (whatever is the mesh shape).
Anything wrong ?
