The text object is rather strange when interior_texture is used
There is an inversion between the paper and the extrusion side.
It's "interesting", but probably not was intended. Some normal might need to be
flipped

"Paper"?

Some code might be helpful to understand what's going on.

the planar side, which might be seen as the paper.

Yes.

I woke up this morning thinking about these prism the text face normals
- and the internal intersection mechanism Christoph added for the
spindle modes of the torus.
I'd been thinking we should just get the "face/end" normals right. What
if we do that by bounding those faces internally using an intersection
with a basic perpendicular linear prism with the appropriate point order.
We could then, somewhat by side effect, offer a face-invert feature & a
quick way for users to get a different texture on the faces via the
inside_texture.
Lots of paths I guess, just wondering this morning if we are not too
looking at a chance for a new prism/text feature with the flat faces.

I fixed it in hgpovray :
https://github.com/POV-Ray/povray/commit/2595932240ea8caa99b2a9c610c8af9d90ff0558
The change might need to be adapted for the master branch (as vector have changed)
