I haven't been following this thread, but as I have pointed out on
this list before, the standard way to set up an arbitrary 3D rotation
is not Rx*Ry*Rz but Rz*Ry*Rz (Euler angle rotation). (Some people use
Rz*Rx*Rz which is essentially the same.)

There is an alternative approach, using quaternions, which provides
the formula for a rotation through a specified angle about a specified
axis.

I suggest that Jmol should use one of these standard, well-documented,
approaches rather than introducing something different.
