/*! Modified Pluecker ray/triangle intersector. The test first shifts
 *  the ray origin into the origin of the coordinate system and then
 *  uses Pluecker coordinates for the intersection. Due to the shift,
 *  the Pluecker coordinate calculation simplifies and the tests get
 *  numerically stable. The edge equations are watertight along the
 *  edge for neighboring triangles. */
