Step characteristics on raster maps (Mathieu Basille)

Dear Arnaud,

This is actually on my todo list, a test with the polygon approach, 
although I'm not sure how to start to "polygonize" the segments... But 
in the end, that would allow a performance comparison with different 
approaches (and that would also allow the calculation of the 
characteristics of buffers around the segments, which might be 
interesting for us, too).

Thanks for the suggestion,
Mathieu.
