I never heard of this! So, possibly the detour via the ASCII matrix is 
not longer necessary?

Yes, otherwise there wouldn't be that strange diagonal scarp... must be 
a mistake in J. M. Bergers correction of my original version (using a 
traditional mesh rather than mesh2). I'll soon try it out (the indices 
obviously must be set to 1200 x 1200 x 2, not 1199 x 1199 x 2!), but 
firstly, I have to complete the download of the current Java API ;-)!

See you in Khyberspace!
