Well, that was the original intent: mapping. However, it could be used for
displacement as follows:

#declare displacementmap = pigment {
...
}
#declare displacementamount = 3;
warp {
    function{x+displacementmap(x,y,z).red*displacementamount }
    function{y+displacementmap(x,y,z).green*displacementamount }
    function{z+displacementmap(x,y,z).blue*displacementamount }
}

Unless I'm misunderstanding how the displacement maps work.

As the other Chris pointed out, POV-Ray doesn't support user defined vector
functions. If it did, that'd be great and I'd use them... but I'm not really
in the mood for implementing them right now =)
