Add example images and descriptions for use cases
of the Ray Portal BSDF.

There are two examples:

  • Ray augmentation (shifting and rotating the ray that hit the portal)
  • Ray replacement (fully replacing the ray position and direction)

Preview can be found here: https://projects.blender.org/Alaska/blender-manual/src/branch/ray-portal-example/manual/render/shader_nodes/shader/ray_portal.rst

If you would like me to adjust framing on the renders, then let me know, I have the .blend files.

The images have been saved as 90 Quality JPEGs. I still have the original PNG files, so if you would prefer a different quality setting or file format, I can change them.

Wow, these are really nice examples. We can use them in the release notes too.

For the layout, I think it's better not to put images side-by side to keep them readable without zooming. I think that's what we do for most node docs.

So perhaps organize something like this?

Along with augmenting rays, the ray position and ray direction can be replaced,
allowing the creation of effects like a camera feed on a screen.
