As requested on our mailing list and despite that a way too long missing feature of our surface mapper is to allow setting the point size for rendering. We already have a property for the line width. Implementing this feature is trivial and it wont affect existing behavior. It's done with a very few lines of code which can be C&Ped from our line width code anyways.

In addition to the already existing line width property I would just introduce a matching property for the point size, i.e.:

material.wireframeLineWidth
material.pointSize

Which just affects a vtkProperty->SetPointSize() call. Range checking is done by OpenGL so we don't have to worry about that (just like the line width property).
