What option?

The mapping warps were never designed to apply to an object with any
alignment in space. Thus the mappings can't be used for the purpose of
mapping the square from <0,0> to <1,1> onto any sphere or cylinder without
considerable work from the user. That's why I want it to be an option
directly implemented in the macros.

Look where? Where can I find the definitions?

By the way, "cylinderical" is spelled wrong and the wrong spelling seems to
have made it into the documentation. The correct spelling is "cylindrical".
