[Kst] Image data type

[Theodore Kisner]

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 :-)
