Comment (by Saul Baker):

 Replying to [comment:11 Michael Koch]:
 > I think that's only possible with one rotation axis. If you rotate
 around two or three axes simultaneously, then it's very complicated to
 calculate the required steps. I don't see any workaround for what was
 possible before the v360 filter was broken. It's a pity.

 Separate [enter]s against all three interleaved in the same file seem to
 work quite happily, if jerkily, although I admit I've not gotten any more
 analytic with it than looking at a virtual lamppost and then flailing
 around wildly to get a good number of rotations to stack.
