[QGIS-Developer] Scale/Magnifier/Units per pixel

[Denis Rouzaud]

Thanks Nyall.

There is a remaining issue though
https://issues.qgis.org/issues/17695

I think the implementation was not perfect, and I guess should belong to
the map settings rather than the canvas.
I tried to fix it for 3.0 but failed.

Cheers,
Denis
