- adds a new point class * point/ vector math (p + v = p, p - p = v, etc.) * points can be transformed by matrices/quats * wraps 'place vector' type vectors that have no magnitude - wrapped toXXX() methods work correctly * toXXX() will NOT wrap data (this is due to the fact that wrapped data cannot be converted) * added a 'wrapped' attribute to mathutils classes to determine wether the object is accessing python or blender data - added the ability to negate vectors/points with "-vec" * deprecated vector.negate() - added the ability to shorhand inverse matrices with "~mat" (tilde) - conversion between vector/point with toXXX() methods
