This changelist adds a visually-motivated example material for the `hextiledimage` node, providing a reference point for future language implementations and improvements. For visibility, a note about missing implementations of `hextiledimage` and `hextilednormalmap` in MSL, OSL, and MDL has been added to the README.md for the MaterialX data libraries. The two new image assets are from ambientCG (https://ambientcg.com/), which shares them under the Creative Commons CC0 1.0 Universal License (https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/THIRD-PARTY.md#ambientcg-assets). One image asset from very early MaterialX examples (marble.png) has been removed, as it no longer appears to be referenced in our repository.

Since the hex tiling technique becomes clearer when it's in motion, here's a quick video showing the visual impact of each input to the example material: OnyxHextiledExample.mp4 |

Looks good to me - I did leave a small question/suggestion below - but I don't think it's important enough to block merging here.

Do you think it makes sense to start to use openPBR for all new tests/examples? I might send a good signal to the community that it is the shading model we hope to see people migrating towards?

I was thinking along those lines too, @ld-kerley, and my main hesitation was that both OpenPBR and Hex Tiling are relatively heavyweight features in real-time shading, and combining them might make it less straightforward for users to discern which feature was responsible if they encounter performance issues.
As both techniques are independently optimized in MaterialX GLSL, we should definitely aim to combine them in future examples of best practices.
