Add support for KTX textures and KHR_texture_basisu?

[echadwick-artist]

It would be helpful if the glTF Validator supported KHR_texture_basisu and mimeType:"image/ktx2".

Currently the validator reports multiple Warnings and Infos related to KTX2, and thus does not list the dimensions of the bitmaps, among other useful infos.

The Stained Glass Lamp sample model includes an example with KTX2 textures:
https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/StainedGlassLamp/glTF-KTX-BasisU
This model has the basisu extension listed in both extensionsUsed and extensionsRequired, because there are no fallback textures. (see #157)

Thanks!

This feature is going to be included in the upcoming validator release.
