#2795 splot round(x) bug...

[Anonymous]

Doing a:
set pm3d map
splot round(x)

on windows 6.0p2 gives strange extra bands near the edges of the rounding (we expect bands from the rounding but it has too many bands, and setting isosamples 1000,1000 or higher doesn't seem to help), whereas doing this same on linux 6.0p2 (compiled) seems to work ok. Was similarly broken on linux 6.0p1 I think though...
