Support compressing KTX2 textures without CLI

Is your feature request related to a problem? Please describe. I’m in the process of updating from 2.1.7 to 2.4.2 (due to the toktx command changes), but running into what looks like “incorrect but somehow working” use of the library.

In 2.1.7, we were using something like

import { NodeIO, PropertyType } from '@gltf-transform/core';
import { draco, toktx } from "@gltf-transform/cli";
...
await document.transform(
		// see https://github.com/donmccurdy/glTF-Transform/blob/main/packages/cli/src/transforms/toktx.ts
		toktx({ mode: Mode.ETC1S }),
		draco(),
);

It looks like in 2.4.2 draco has moved into /functions, but otherwise this still works.

How can we use the simplicity of the toktx command but not depend on the CLI? Might be missing something obvious here!

Yep, we were. We also ended up doing what you recommended and moving the toktx scripts out of the CLI package into our own, to get rid of the CLI dependency.

@hybridherbst were you able to get the v2.4.2 update working?
