About this refreshed version:

1. The Planet matrix as been collected/collapsed for stand alone document.
2. It has been cleaned from source from random non zero in the background.
3. It demonstrates the normal vectorize over a scalar function vs Vectorize(data,algo)
for non-scalar [linterp, ainterp, cinterp ... maybe erf(x) ?]
4. Download, F9 ... done ~ 6 min in my machine.
5. Strictly demo/initiate image stuff.
