Yes, the vrotate() function is part of the official version. However, 
the vtransform() function isn't, it is a patch that I wrote, but it is 
in MegaPOV and will eventually be in POV 3.5. You could imitate it 
partially with macros, like:
#macro VTranslate(V, Translation) (V+Translation) #end
#macro VScale(V, Translation) (V*Translation) #end

Another function in the official version that you may find useful is 
vaxis_rotate(), which rotates a point around a given axis by a specified 
number of degrees instead of x, y, then z.
