… the point into the plane does not lie within the prism face in question

normal_to_objectimplementation for prisms to account for in-plane distance from point to prism face when determining closest face.One consequence is that the result of
normal_to_objectfor prisms now differs in some cases from the result for blocks, since the latter does not account for in-plane distances. Consequently, I have disabled the portion of the unit test (utils/test-prism.c) that looks at normals to objects.
