[vtkusers] Texture mapping a cube

[Bill Lorensen]

TextureMapToPlane only generates texture coordinated for planes or
nearly planar objects. A cube is not planar.

There are a couple of approaches.

1) Build your cube from six planes. Texture coordinates for each plane
can be genearted with TextuteMapToPlane
2) Imaginge your cube is unfolded. Create a texture map that
corresponds to the unfolded cube. Here is a website that shows a few
cube maps:

Then you will need to generate your own texture coordinates.
