[Chameleon] Rounding scale value

[Gambin Dejan]

I have tried nad it seems it work for me...but I just modified this
piece of code because I am just interested in showing the scale value
without any decimal points. I suppose you are interested in adding a new
parameter in a widget...

regards, dejan
