Hi Dave - actually that selection.filter doesn't do anything at all.

It was just an early start on a filter controlling mechanism, but it never actually got anything hooked up to it.

The idea was going to be that you could switch between some filter modes: Auto (with the drill-in mechanism for selecting sub-objects as it currently works), Face, Edge, or Curve.

Now I have kind of a vague idea that implementing selection filtering may be better incorporated into the scene browser - it has a "Types" section that lists that same kind of entity categories, but also has things like styles in it which could be useful to set as a filter as well.
