Subject: update Transform::inverse() to take an optional argument stating
 whether the transformation is:    NonAffine, Affine (default), contains
 NoShear, contains NoScaling that allows significant speed improvements. If
 you like it, this concept could be applied to Transform::extractRotation (or
 to a more advanced decomposition function) and to Hyperplane::transformed()
 and maybe to some other places... e.g., I think a Transform::normalMatrix()
 function would not harm and warn user that the transformation of normals is
 not that trivial (I saw this mistake much too often)
