[Therion] Altitude colors range

[Footleg]

I am not seeing this Bruce. I just tested with 5.3.16. My survey imports
the centreline from a Survex .3d file however, so that might make a
difference? Or maybe I am not understanding what you mean by including the
centreline in the map. I turned off the centreline using 'symbol-hide line
survey'. If I comment that out in my layout then the centreline is drawn in
the map, but my altitude range still covers only the range of my scraps.
