Oh, you wanted to apply it to an input vector? Well I wrote something for that too!
:))

Looks right. The last two lines that modify pt can be comnbined: vrotate ( pt,
<-RotX,RotY,0> )

Basically the more control and more errorproofing you want the more sloppy code you'll
have to write. Basically my macro finds the rotation values (spherical vector) of the
vectors and undoes the first one and applies the second.
