[Therion] Sketches on doesn't work / legacy survey

[Roger Schuster]

Hello again,

finally I got it working and if I compare the output of Therion with the 
original map on paper there is only a tiny bit of distortion. Both maps 
match quite nicely. There are just two things I don't understand:

There is a white, trapezoid gap on the map which isn't on the background 
image (of course). I guess it has something to do with the morphing - is 
there a way to get rid of this artifact?

I also noticed that length and depth statistics in the map header 
(registers \cavelength and \cavedepth) are wrong while in the log file 
it's right. The values in the registers obviously depend on which 
stations / surveys are marked and to get the same values as in the log 
at least one station of each survey has to be marked (unfortunately each 
mark results in a more or less ugly white trapezoid as mentioned above). 
This is the reason why I decided to override the registers in code 
tex-map.

Unfortunately I can't post the map here because of copyright reasons.

Best regards,

Roger
