Remove threeCompatibilityTransforms

[mrdoob]

I think these can be removed now?

Lines 808 to 816 in 0b9ffc9

	### .threeCompatibilityTransforms
	```js
	threeCompatibilityTransforms = false : Boolean
	```
	Three.js materials support only a single set of UV transforms in a certain fallback priority while the pathtracer supports a unique set of transforms per texture. Set this field to true in order to use the same uv transform handling as three.js materials.
	See fallback order documentation [here](https://threejs.org/docs/#api/en/textures/Texture.offset).

Oh is this fixed? Nice! So every texture will use it's own transform matrix in three.js, now?

[gkjohnson]

@mrdoob Do you recall which version of three.js this was fixed in? I'll want to update the minimum peer dependency.

It was r151. mrdoob/three.js#25721 (comment)
