Description

The attached 'patches' allow fTools to produce Voronoi polygons. To ease checking, I have marked new/changed lines in voronoi.py with my initials (AJS). The changes in doGeometry.py are straight forward, but a new ui and QGIS menu changes are obviously also required.

Other than fixing a bug, I have not altered how voronoi.py handles edges that run to infinity. Polygons can extend way beyond the bounds of the point layer (10 times the size!).

It would be nice if the ui allowed the user to specify an attribute in the source layer (e.g. id, name) to add to the associated polygon

Addressed in 8710328b (SVN r14745), although I did not use the attached patch. The new implementation allows for clipping the voronoi tessellation to a predefined region around the input points.
