Support for loading these formats in KTX2Loader to be added in: As a bit of motivation — any of the .cube 3D LUTs from this example can be reduced from 880kb to 130kb by using .ktx2 3D textures instead. That's without supporting zstd supercompression, which would likely reduce their size further. |

@donmccurdy do you know which ktx-parse commit the built ktx-parse.module.js embedded here is from vs the previous version? I'm investigating an issue with loading my ktx2 files after a recent three upgrade that seems to be introduced here. |

Pardon, forget that, the issue ended up being user error on my end after all ! 👋 |

Adds support for exporting KTX 2.0 textures in uncompressed formats.
✅ Included:
I hope to add support for lossless supercompression (likely ZSTD) in the future, but implementing Basis Universal compression here is not something I'm currently planning to work on. This PR is focused on lossless encoding of data textures, for somewhat different purposes. Perhaps GoogleChromeLabs/squoosh#1017 will be completed at some point for Basis Universal compression in web applications, that is a larger task.
