Not really.  In what I expect to be the most frequent data patterns for 
pm3d plots (regular, x-y aligned grids of data), point-like 
depth-sorting will typically produce worse results than the currently 
existing output patterns.   Scansbackward and Scansforward are not bad 
at all, for this kind of data.  One of them will be exactly correct.

To sum it up a little aggressively: z-sorting, scansbackward and 
scansforward are all about equally wrong, but are also each necessary to 
get a correct display in *some* case.
