splot and surface visibility

[Mojca M. <moj...@gm...>]

Hello,

there's a serious problem when drawing 2D surfaces in 3D space.
Consider the following two plots:

set palette gray
splot 10*sin(x) with pm3d, x*y with pm3d
splot x*y with pm3d, 10*sin(x) with pm3d

The two surfaces are simply plotted one over another without
considering proper 3D placement and visibility. (The two plots should
be identical, but they aren't.) Will there be a remedy for that
anytime in the near future? (Fixing that would probably require
rewriting quite a lot of code.)

Thanks a lot,
    Mojca
