Or the OTFR dialog could already produce a list of available transforms for
each CRS used in layers - maybe with the last used transform for each
combination preselected.

Is that really significant?  I suppose using the same connection as syncDb()
would help (just because it does it's thing in a transaction).

Who's bad idea was it to call that thing tr()? ;)   transformation() is
probably better for a public method.

Why is it in a separate branch?
