#4 problems with some symbols

[Tõnis Eenmäe]

I used last version of mapper3 and noticed some problems:

1. Water-type rooms are marked only with blue colour.
It is OK with coloured maps, but very poor with b/w
maps. Actually, rivers just disappear in B/W mode. Gray
maps use special symbol for rivers, it is much more
usable in BW mode. If there is a possibility to use
again this water sign (maybe so that 'w' produces still
blue square but some other key produces "waves"), it
would be very nice :-)

2. Quite serious is problem with dark rooms. If you
look at Gray's maps, dark rooms are just light gray.
Any signs and text on this colour is very well
readable. In latest mapper3, there is some black raster
for dark rooms (produced with SPACE key) - it causes
trouble even for colour-mode - it hides exits and other
symbols (specially, when one uses 1/4 mode for u/d
exits and aggressive mobs). I add an example "map" too.

I thought a bit about possibilities and found that
maybe dark rooms could be marked with some continuous
light gray (different from mountains) - all signs are
then readable.

Otherwise mapper is really useful program :-) Thanks a lot!
