// WARNING: Possible bug for sammTrim2
// There is a possibility that the lookup table for SAMM shapes is based on
// the rotation of the shape. This would imply that the table below would need
// to be split between the regular shapes (3-9), which are OK, and the SAMM
// shapes, for which the face lookup needs to be done based on the rotation.
// However, at the moment I haven't got enough info to complete the toble and
// there are no cases that break it. Please reconsider in the light of mode
// information.
