This changelist introduces an NPR (non-photorealistic rendering) data library to MaterialX, initially consisting of a single `viewdirection` node. The NPR data library is designed for the portable expression of artistic, non-physically-based materials, with common examples being cartoon shading, architectural diagrams, and edge highlighting. In future versions of MaterialX, we expect this data library to be extended with additional primitives and artist-facing graphs as they are requested by the graphics community and approved by the MaterialX TSC. For shader generation, MaterialX initially supports the NPR data library in GLSL, ESSL, MSL, and OSL, with MDL being omitted for now, based on intentional restrictions in its design philosophy.

This changelist includes a handful of very simple NPR examples, including Edge Brighten, Environment Map, and Starfield, in order to test implementations and evaluate parity across languages. Artists are encouraged to create their own examples, and we'd be happy to include them in the future!

Very excited to see this work towards nprlib. Thank you!! |

As suggested in review feedback, this commit moves environment_map.mtlx back to the resources/Lights folder, so that the MaterialX Viewer doesn't gain a dependency on a new folder.

* Add enumeration support to web viewer (AcademySoftwareFoundation#1632) - Scan for `enum` and `enumvalues` if attributes exist on input. If no `enumvalues` exist then map to "default" of 0..<enum list size>. - Create a drop-down for each enumerated input. * Initial nprlib with viewdirection node (AcademySoftwareFoundation#1631) This changelist introduces an NPR (non-photorealistic rendering) data library to MaterialX, initially consisting of a single `viewdirection` node.
