[Qgis-developer] Vector Layer Generalization

Excellent! Topology preserving simplification is something I've been
looking for!

Personally, I normally simplify an entire layer at once... for mapping
purposes, or simply to reduce drawing time or for computational/space
efficiency. It might be nice to also have the option to simplify
selected features only, but if this was an option, then I would expect
*only* those selected features to be simplified... and *not* their
neighbouring features...

That's my two cents anyway, looking forward to trying it out!
