Oh I was under the impression you made a strategy object for the
different kinds of scale computations? In which case it would of been a
new API. My mistake.

So when the code gets around to calculating do you have an "if"
statement to choose between
the different techniques?

Okay so there is a Jira item that is marked closed for 2.2.3 and forward
then ...

Great :-) Well this is exactly the sort of thing we want to tack (if
only with a Jira) so that the "trunk on trunk" idea
works out for everyone.
