GLTF's UV scale functionality not implemented in 1.16.0?

[vortice3D]

Hi there:

We suspect that Sceneform (1.16.0) does not deal (properly) with UV Scale in GLTF/GLB files.

As a background information, this kind of transform is carried-out by means of the GLTF 2.0 extension KHR_texture_transform, so maybe the issue is indeed a fault of Filament 1.4.5 (the one used by Scenform 1.16,0).

Said this, when I use this kind of UV Scaling in a GLTF scene in order to obtain a repeatable large texture, I'm getting things like this:

Please note the wrong repetition problem in the platform and the rail.

Of course, the texture is shown in a correct way when we visualize the GLTF by means of a WebGL viewer (e.g. VSCodium GLTF Extension):

Best regards.
