[Squeakland] 'turn toward' behavior

[Randy Heiland]

I just discovered that the 'turn toward' tile only works as expected if the
2 objects in question (e.g., a turn towards b) do not overlap.  This seems
like a bug to me since, I believe, the 'turn towards' operates on the
centers (rotation centers), i.e. single points, of the objects in question
and, hence, may have nothing whatsoever to do with the objects' pixels.
