> I don't understand this discussion. Vertex labels can be plotted for all
plottable types. The problem is that when plotting e.g. a scalar field in
2D as a warped surface, the labels are placed in a single plane (on the
mesh itself, but it is invisible) rather than on the warped surface. I
think we should fix the label placement or disable labels when plotting
functions.

I also suggest extending the GenericVTKPlottable interface with a keypress
handler and a helptext method, to facilitate plot type dependent user
interaction.
