tapered surface tools

A lot of f1 (and I am assuming other model) users are engraving on tumblers or glasses with a tapered surface.

The math to adjust things to a tapered surface is not hard to implement, and having it included as a tool in the design space would seriously reduce the back and forth to other programs.  

Ideally you would define the entire surface area (top circumfrance, bottom circumfrance, hight) and then when you place a graphic, text box, shape within that space, the design space would stretch/squich the edges so that it will burn/etch/trace without distortion ont he surface in question.

Alternatively, just adding the ability to arbitrarily change the length of each side of a parallelagram stretching/squiching the text/picture/shape within to match would make everything easier without implementing the math.
