Hi,
i wrote a small Patch for the Scale-Control. The possibility to shorten
the scale values is good and can be the default - but sometimes the
exact values are needed to be shown to the user. In the patched version
it is possible to switch between shortening mode and not shortening mode
by the shorten property.
