stoofin 8abd64dcbb Fixed bug caused by a copy/paste error in Face3::get_closest_point_to ...

s * edge0 = -d / a * edge0 = -edge0⋅v0 / (edge0⋅edge0) * edge0 = vector projection of -v0 onto edge0

By incorrectly using -e/c instead of -d/a, Face3::get_closest_point_to was returning the wrong point in certain cases.  Specifically, I noticed it returning vertex[0] when it should have been returning vertex[1].
