Feature ID Texture With Texture Transform

The test data for https://github.com/CesiumGS/cesium/issues/11731 :

It is a glTF asset that only contains a unit square.

It uses the same texture for the base color and for a Feature ID Texture: The texture just contains 8x8 pixels with increasing 'red' component values: The red components will be [0 ... 64)3. (Meaning that the lower right pixel will have a red value of 633=189).

So the base color will be (black ... red), and the feature ID values in the property texture will be in [0...189].

It uses the same texture transform for both usages of the texture, namely with an offset of [0.25, 0.25], and a scale of [0.5, 0.5].
