Using v4.4.3, I am trying to control colors of two sides of a surface... 
but I can only set one color. Here is an example:

---
set terminal pdf size 6,5 enhanced

set style line 1 lc rgbcolor "blue"
set style line 2 lc rgbcolor "black"
set style line 3 lc rgbcolor "red"

set hidden3d offset 1
show hidden3d #says "Back side of surfaces has linestyle offset of 1"

splot sin(x*y) w l linestyle 1
---

The "linestyle 1" part selects a color of *both* sides; the "offset 1" 
does not seem to work. What am I missing?


Thanks,

Maciej
