Hi,
While rending a generated script, I get:
File: test.pov Line: 16077
Parse Warning: Points in polygon are not co-planar. Ignoring polygons.
The line is:
polygon { 5 <110, 25, 2>, <111, 25, 2>, <111, 26, 3>, <110, 26, 2>, <110, 25, 2>
texture{pigment{rgb <0, 0.461435456673892, 0.443295311143663>}} }
What is wrong and how can I fix it?

Yes, ok, but how do I fix this?
Should I split it (it is a square) in 2 triangles? Or do the same rules apply?

Your problem is that the polygon is not a square. It would only be a square
if it was coplanar. Coplanar means the points are in one plane (which does
*not* mean the plane has to be axis aligned!), as otherwise the polygon's
plane is not fully defined - imagine a sheet of paper that you hold on to
diagonal corners. Depending on which corner of the two possible diagonal
corners you pick, it will be a different shape. The same problem exists with
a polygon with more than three corners. You have to pick the corner
coordinates properly for it to be in one plane.
See:
<http://en.wikipedia.org/wiki/Coplanarity>
You can search for the error message:

Look at the third point Z coordinate... It's 3, all others are 2.
