Basis support inside KTX2 container

[vorg]

Is there plan in enabling basis transcoder in KTX Loader inside CompressedTextureLoader in order to support basis in gltf files as per KHR_texture_basisu?

Short answer is yes. That said, we are focusing on basis support in I3SLoader at the moment, which doesn't involve glTF, but the required glTF changes do not look big.

Let's see if we can get this into ongoing 3.0 development (which we plan to release towards end of April). Can't guarantee at the moment but it makes a lot of sense.

PRs are welcome :)
