My apologies.   I had thought the discussion was about Euclidean

Agreed, and I agree with her point on that also.  However, I still stress the
need for "finesse".  Students, still having open minds about what they see and
absorb, need to see from the start what is as close to the reality [albeit
abstract] as possible.  So I comment again that drawn lines should be as thin as
is reasonable, and not be thick blotches.  If that were the only means of
drawing constructions on that medium, I would abandon it, momentarily, in that
case in favour of something more favourable.
