In February of 2008 Tim Schaub sent an email about a patch in his sandbox
that used a minkowski sum (I think) to create a client-side buffer. The
end results typically had self-intersections. He mentioned that an
upgraded version(as an external library) might be on the way that included
polygon simplification to remove the self-intersection. Does anyone if
this was ever released? If not, does anyone have any suggestions for an
algorithm that could remove self-intersection? I don't think convex hulls
would work because I think the resulting buffer would lose all detail.
Sorting the vertices clockwise using atan2 didn't work either.
