18.3.0

• Bugfix: MyQuaternion.isRotationIdentity() accepts NaNs
• New capability to dump physics objects for debug purposes, which entailed addition of the following classes/methods from Heart/Minie:
  • Describer
  • Dumper
  • DumpFlags
  • MyBuffer.frequency()
  • MyPco
  • MyQuaternion.describe()
  • MyString.axisName()
  • MyString.describe()
  • MyString.describeFraction()
  • MyString.describeMatrix()
  • MyVector3f.describe()
  • MyVector3f.describeDirection()
  • PhysicsDescriber
  • PhysicsDumper
• Better 3-D rotations and transformations by adding 5 methods from Heart:
  • MyQuaternion.rotate()
  • MyQuaternion.rotateInverse()
  • MyMath.combine()
  • MyMath.transform()
  • MyMath.transformInverse()
• Deprecated the corresponding math methods:
  • Quaternion.multLocal(Vector3f)
  • Quaternion.mult(Vector3f, Vector3f)
  • Transform.combineWithParent()
  • Transform.transformInverseVector()
  • Transform.transformVector()
• Other methods added:
  • GImpactCollisionShape.countMeshTriangles()
  • Transform.setScale(Vector3f)
  • Validate.standardAngle()
