Well - then you would have to be able to give me an example of a POV-Ray 
shape where you can modify the analytical root solver to support 
displacement mapping.  As long as you don't i keep my statement that 
this is not possible (and i am quite sure about this).

Is what i write somehow impossible to understand?  If not i have no idea 
why you post such a reply.
