 This is related to the core of MapServer, but is important for the Chameleon
Widget ScaleBar. I want to first see what the developerís first thought before
it becomes a MapServer issue.

The basic Idea of this bug is to make the ScaleBar be able to display more
cleanly from zoom threshold to threshold. Often the scale bars number overlap
due to the interval size.

The Scalebar does use scientific notation, but it is brought in to late for the
notation to be useful.

The intervals set by the user should be a guide for the Scale Bar on what to
display when the to how to display rather than the static display for the scale
bar. The length of the text should be balanced with the intervals.
