17.4.0

• Bugfix: transforms not updated for the getCalculatedOriginA() and getCalculatedOriginB() methods in the New6Dof class
• Bugfix: Quatd.isRotationIdentity() accepts NaNs
• Bugfix: toString() fails for an unassigned PhysicsCollisionObject
• Bugfix: PhysicsCollisionObject.copyPcoProperties() results in different collision flags
• Added 4 new methods:
  • New6Dof.calculatedBasisA()
  • New6Dof.calculatedBasisB()
  • PhysicsCollisionObject.collisionFlags()
  • Vec3d.isFinite()
• Reduced the likelihood of hash collisions in Matrix3d.
• Made the result of PhysicsCollisionObject.toString() more concise.
