That shouldn't be too hard.

Aside from being highly complex to implement, this would probably slow 
things down a lot. You'd be better off resizing outside of POV, and 
using a computationally cheaper method in the rendering.

This one has been discussed a *lot*. To summarize: it is possible, but 
is far from simple. General displacement would require tessellation of 
all objects, which is possible but a real pain to implement.
