IMHO the render order should be considered arbitrary. The provider doesn't
return the features in a particular order later anyway.

Currently (w/o Matthias patch) while the layer is edited feature with changed
geometries are rendered first (ie. bottom), then added features and then
features from the provider (- those that are going to be deleted).

I don't think that this must be changed.  If a layer can have overlapping
features, it probably should be configured to show them transparently already.
