# projection_direction broken for polytopes?

Some years back (probably 2 or 3) Marshall very kindly sent me a notebook of polytope commands. In that notebook there were the following:

```
poly = polytopes.twenty_four_cell()
poly.show()
poly.show(projection_direction=[2,5,11,17])
```

These last two commands produced different green diagrams... two years ago. Today, they produce identical blue diagrams.

I search "sage projection_direction" and http://www.sagemath.org/doc/reference... seems to indicate that the projection_direction option is still valid (not deprecated? should work? what's the correct phrasing here?).

Anyone know what's up with that?

Update: http://trac.sagemath.org/ticket/16625 now has a fix (and then some!) for this issue. Reviewers needed!

And has positive review, thanks Andrey.
