It's easier  :-) , but it will look worse  :-(

We do need to solve this problem somehow. Current rock-drawing is
super-slow, but I want my finished rocks to look realistic as well (i.e. not
sticking through the walls).

Do the UIS have different symbols for this? clay is indeed sediment with
very fine particles. I think of there being 'dry sediment' (sand symbol) and
'wet sediment' (mud symbol). I think that's plenty for my purposes, but
Therion just needs to provide whatever the various symbol sets provide.
