This is because maps "wrap around" at 1, with the value exactly equal to
1 not being represented in the map.  Something with slope exactly equal 
to 1 (well, not really, but you know what I mean) will use the value at the 
0 end of the map.

A temporary workaround is to use 

      color_map{
        [.000001 red 1]
        [.000001 rgbt 1]
        [0.5 rgbt 1]
        [1.0 red 1]
      }

instead of the color_map you had.  This is technically correct behavior,
but it's worth discussing whether the slope pattern should be an exception
to the rule.
