[Therion] Therion legend and symbols

[Bruce]

Hi 
I've just got interested in tweaking my legends and have some questions.
 
1  Removing legend entries
----------------------------------------
I notice that there is no legend entry for 'label' or 'remark', although
there are entries for these in the texts.txt (5.3.8) file in the sources.
This seems quite sensible to me, as it is generally self evident and no
legend entry should be needed.
 
I think that 'arrow' fits in the same category.  It seems a bit redundant to
have an entry for 'arrow' in the legend.  
Is there a way for the user to supress particular legend entries?
 
I tried;
text en "line arrow"    ""
to suppress the legend entry, but predictably enough all i got was an arrow
with no label!
 
(see the somewhat modified legend attached)
 
2 New area legend entries don't want to change
----------------------------------------
I tried to modify the new 'area flowstone' and 'area moonmilk' legend
entries, but I get an error.  There must be something different about them.
eg
text en "line wall:clay"         "clay, mud"
text en "area clay"              "clay, mud"
#text en "area flowstone"         "flowstone"
#text en "area moonmilk"          "moonmilk"
text en "point gradient"         "gradient/slope"
 
If I remove the #'s I get an error.  My mistake or is there really something
different about the new entries?
 
3 New entrance symbol
----------------------------------------
I'd like to change the entrance symbol from a filled triangle to, say,  an
omega symbol (as is already used for station with flag entrance).
Has anyone come up with some metapost for this? Or another way of doing it?
 
4 Survey station with specific flags in legend
----------------------------------------
I notice that the legend is set up to display and differentiate survey
stations with 'mark fixed, 'mark painted' etc but not to differentiate for
flags such as entrance, doline, arch etc.
Is it possible to include 'flagged' survey stations in the legend?
 
Cheers
Bruce
