(issue1579) Fix axes syncronisation at Gauges The SyncNumberAxis was completely broken. It only synced in one direction and even that did not work correctly when data was added to the axis (and the syncAxis rescaled but forgot the old axis) then there were lots of ways to bypass that scaling. And i also think the trans calculation was wrong. It has been replaced by a "mostly" simple method to just keep the W in M and W in CM+Datum axes in sync. I say "Mostly" because it had to deal with the Bounds interface.
