[Bf-funboard] Slice Modifier

[Campbell Barton]

Hi, this is a modifier I just made a patch for that cuts a solid mesh 
into slithers.

The functionality is fairly obscure so Im not sure it should go into 
blender or not... though of course Id rather my work didn't go to waist ;)

Heres what it does
* cuts a mesh on the x/y/z axis into slices
* adjustable slice gap and offset
* supports multiple materials (per solid region)
* an object can be used to adjust/animate the slice axis and gap (with 
scaling)
* works with negative space (a cube inside a cube will slice into a 
hollow shape)

* does NOT work when there are holes in a mesh (Those thices will be 
omitted)

It can be used to do fake volumetric rendering (with internal texturing) 
or as an effect.

Here are some examples of its use
