[Therion] Area border problems

[Wookey]

The latest version of terikan.pdf and terikanatlas.pdf are at
http://wookware.org/mulu/

I have now understood the use of select and maps to get the layers and
previews I want (cool!)

Some queries:
1) Why can I click on the internal hyperlinks in the preview map windows
and the level labels ('high level passages' etc), but not the
page-numbers indicated to N,S,E,W ? They all work on one of the
example atlas maps. Do I need to add a rune to enable this?

2) Area problems: See the river (blue :-) ) on the upper half of the survey,
'riverlelvel passages'. (easier on the single-sheet survey).

Between the labels 'Arrow inlet' and 'River passage' there is a 25m
diameter rock pillar on north side which has got coloured in blue. I
tried reversing the line but it's still deemed to be part of the water
area. Why?

A bit further east the area has inlcuded a couple more rock pillars
and a mudbank that should be between them. This bring up the whole
issue of pillars inside areas. What is the correct way to indicate
these? (There are quite a few rocks in the river with a similar problem.

Further easy still (just before 'sump three') the area has gone all
strange where it should be bounded by a mudbank border and some rocks.
I'm not sure what is going on here. This whole area is a complex one
with a lot of edge segments.

3) Currently if a passage is coloured then all the closed loops within
it (blocks/rocks/boulders) come out with a double-tint as the colour
is presumably applied twice. I don't think I really want this - rocks
should be the same colour as the passages they are in. How do we fix
this?

4) river colour. How do the metapost colours work. 3 RGb values?
rising or falling? I want to make the river/water a much lighter blue but I
tried fiddling with the numbers and above (0, 0, 0.95) was as good as
I could get. Perhaps what I really need is some cyan, or maybe a
transparency/saturation setting. Suggestions? 

That'll do for today :-)

mulu.tgz contains a tarball of the cdata with e all the pics and maps
and other huge files taken out.
