mapserver-5.0.0-rc2 scale issues

[Stephen Woodbridge]

Uggh,

I thought we had this problem fixed but it seems to have regressed 
somewhere:

http://imaptools.com/~woodbri/work/two-maps.html

AGG 5.0-rc2 on the left and 4.10.1 on the right

these two map files are virtually identical, but the scale computation 
on 5.0 is wrong (again) as can be seem by the differences in labeling 
and the level of detail of the roads displayed.

This looks like the same/similar problem as
http://trac.osgeo.org/mapserver/ticket/2166
http://trac.osgeo.org/mapserver/ticket/2193

While the exact test cases presented in those tickets do work correctly 
you can definitely see differences in the link above.

Also, if you zoom into 25k, all the railroad cross ties are broken also. 
They are defined as:

SYMBOL
NAME "railway6"
TYPE truetype
FONT arial
CHARACTER "|"
GAP -6
END

SYMBOL
NAME "railway"
TYPE truetype
FONT arial
CHARACTER "|"
GAP -16
END

Clearly something(s) have changed since I had time to look at it last. I 
think these need to get resolved before release. It might only be my 
config, but I don't think so.
