[mapserver-dev] Scalebar enhancement

[Tamas Szekeres]

I've prepared a commit for the proposed option here:

https://github.com/mapserver/mapserver/issues/5075

Let me know it it does make sense.

I'm still thinking about the option to switch that feature off/on according
to the user preference. We might also think to add this enhancement to the
embedded scalebars only, though I think in most cases the scalebar is used
in embedded mode.

Best regards,

Tamas
