Reading up on the UVPov docs I came across a reference to this:

inside_test_vector z

which is supposed to help for correction in inside/outside mesh testing.

I tried applying it and cannot get UVPov to accept the syntax provided.

Examples of methods tried:

mesh {
      inside_test_vector z
      triangle{...}
      triangle{...}
     }

mesh {
      triangle{...}
      triangle{...}
      inside_test_vector z
     }

#declare MESH =
mesh {
      triangle{...}
      triangle{...}
     }

object { MESH  inside_test_vector z }

Each of the above applications result in an error message that reads
"unknown identifier  inside_test_vector z found bla bla bla...".

The reason I am trying to use this is because my attempts so far in getting
a mesh to work in a CSG operation have failed miserably and I was hoping
that I could use this modifier to work around it.

Use 'inside_vector' instead.  Sorry.  I'll fix the docs with the next
version.
