[scalebar] scalebar fails for large extents

Description 

for a map of canada in an LCC projection (meters), the extents are fairly large,
displaying the scalebar with units of MS_METERS (for instance) causes the
scalebar to "collapse".  Reducing from 3 to 5 intervals 'fixes' the problem, as
does switching to larger units.  It seems to be an overflow problem.

test script to reproduce problem in php_mapscript (will be) attached, although
it can be reproduced with a simple map file too :)

test script may need to be adjusted for local paths.

This exists also in version 4.0 and 3.6.
