Description

Took a first stab at implementing KHR_materials_emissive_strength.
cc @donmccurdy
Got a question as well: for this and other new material features, is there a best practice for testing it in three.js? I'm just testing in my viewer PR, but not sure how that is in general handled.

This contribution is funded by 🌵 Needle.

Excellent, thanks!

Most loaders don't have unit tests, other than the tests against the base class, THREE.Loader. For a sufficiently complex feature I think we'd try to work it into an example where appropriate, though we don't really do examples just as tests.

If we wanted a test on this extension I'd suggest modifying the GLB from our bloom example to use KHR_materials_emissive_strength, but that's certainly not required for this PR to be merged.
