It seems the consensus is to lower the threshold when graphics are changed
to default sizes. I will do an enhancement request next week and propose
that the currrent threshold of 8 by 8 and lower will be reduced to 5 by 5
and lower. That should cover most clone requests and still prevents most
accidental clicks. The double-click delta default is 4 in case someone
double-clicks right away.

If Edinburgh agrees I will do a pull-request.

Kind regards
Bernd
