Fix a chaos bounce crash (#5892).
It wasn't safe to change the angle of a ray that was on a corner of
the 45-degree diamond grid: if the new angle pointed inside the cell,
we would violate the _valid() checks. Have set_degrees (only called
for chaos bouncing currently) nudge the ray inside the diamond to
avoid this problem.
