    Description copied from class: BodyTransformer
    
    This method is called to perform the transformation itself. It is declared abstract; subclasses must implement this method by making it the entry point to their actual Body transformation.
    
    Specified by:
    
    internalTransform in class BodyTransformer
    
    Parameters:
    
    b - the body on which to apply the transformation
    
    phaseName - the phasename for this transform; not typically used by implementations.
    
    options - the actual computed options; a combination of default options and Scene specified options.
