There was a discussion about this about a month ago after I tried r.random
and found that all the points clustered along the top edge of the region.
Apparently it is something to do with how the random function was/is
implemented. For a Mac, it makes the y dimension far too small. Glynn
explained the issue. What I don't remember is if it was fixed in the cvs or
not.
I don't think so. A cleanup is needed (volunteers?)
