To partly answer my question:
It works with a vtkTextActor added to the renderer using a vtkPropPicker.

But if I use a vtkLabeledDataMapper/vtkActor2D, it can't find which 
label was picked, not does it seem to pick the vtkActor2D correctly for 
all possible mouse coordinates if any of the labels were under the mouse.
