 From the documentation it seems like buffering only works for positive 
offsets. Is the complement operation erosion also supported? Erosion is 
important when simplifying structures. It is common practice to first expand 
and then erode to get rid of minor details in shapes.

Also, from the documentation it seems like Douglas-Peucker is the only
available simplification algorithm. Do you have any plans to enlarge
the set of available algorithms? DP is pretty much the worst algorithm
we have available.

Triangulation was not mentioned. However, triangulation is an effective tool 
for simplifying polygons, once you determine what your simplification criteria 
are. Do you have any plans to add triangulation as an elementary operation?
