[GRASS-dev] Re: Line of Sight Update

All of that is already in place and working.  (Well, I don't know if
curvature is working - all the data I have here is in the wrong projection
to work with curvature, but i ported the code from r.los, so hopefully it
should work as expected)  Right now, I'm having some issues with it
determining correctly which mode it should be in (internal memory, external
memory, or a variant of external memory where we distribute sectors) but I
have been running a lot of tests, and hopefully this will be one of the last
bugs to work out.
