Description

Even when reversed, this Or will only accept whichever TupleArg comes first. I was trying to add a consolidated 'center' parameter to the segmentations command. The center an either be the x,y coordinates of a point on a 2D slice or a 3D coordinate.

It looks like that because Aggregate (which TupleOf inherits from) sets its 'offset' attribute, Or does not try the second alternative.

Reproduce with:

from chimerax.core.commands import TupleOf, IntArg, Or
arg = Or(TupleOf(IntArg, 3), TupleOf(IntArg, 2))
arg.parse("1, 2, 3", session)  # works
arg.parse("1, 2", session)   # fails

The offset logic was the problem. Revise to use offset of the longest subparse if none succeed.
