I think it has been asked here before but I can't think of the right 
term. In 2d vector graphics there is a function called envelope which 
allows you to take an object and distort it into any quadrangle.

I am trying the same thing in POV-Ray, but every transformation I can 
pull out of my hat and the include files maintains the original 
parallelogram. I tried slicing a box in half and transforming the two 
sides but it ended up with an ugly crease.

Am I fooling myself into thinking this is even possible in POV-Ray?
