I've just uploaded a patch to graph3d.c which implements the depth patch
also for "set pm3d implicit". Even if pm3d is "implicit", the surface
type has to be specified explicitely on the splot line like

     gnuplot> set pm3d implicit
     gnuplot> splot 'whale.dat' with pm3d

This is due to the fact that when using

     gnuplot> set pm3d implicit
     gnuplot> splot 'whale.dat'

the pm3d surface must be plotted before the default style (which might
be lines for example).
