Several months ago I seem to recall a similar discussion where we were going
to have a Kst3DPlot to do projections of 3D datasets... Would that be a
reasonable alternative to throwing all that stuff into Kst2DPlot? All common
functionality between the two was going to be put in libkst if I recall...
Of course, I've not contributed any code towards this goal, so take my opinion
as a comment from the masses :-)
