[Therion] vthreshold

[Andrew Atkinson]

Hello

Just been play with a feature I have not used before.

First It would be clearer if on p20 of the thbook the paragraph under 
vthreshold

If passages are _more_or_less_ vertical (inclination > vthreshold), even 
UD becomes
perpendicular to the shot – otherwise passages would not look very good.

The 'more or less' is very confusing

It would read better if it read

If passages are _about_ vertical (inclination > vthreshold), even UD becomes
perpendicular to the shot – otherwise passages would not look very good.

Also

In some passages NSEW is not not always the best way to measure 
passages, rifts on the like. So for some I have dimensions measured as 
NW SE NE SW, possible allowing an ofset for vthreshold would be a way of 
solving this. eg

vthreshold-offset 45 degree

Just a thought for the future.

thanks

Andrew
