/**
* Defines how an UV channel is transformed.
*
* This is just a helper structure for the {@link Assimp#_AI_MATKEY_UVTRANSFORM_BASE} key. See its documentation for more details.
*
* Typically you'll want to build a matrix of this information. However, we keep separate scaling/translation/rotation values to make it easier to process
* and optimize UV transformations internally.
*
* Member documentation
*
*
* - {@code mTranslation} – Translation on the u and v axes. The default value is (0|0).
* - {@code mScaling} – Scaling on the u and v axes. The default value is (1|1).
* - {@code mRotation} – Rotation - in counter-clockwise direction. The rotation angle is specified in radians. The rotation center is 0.5f|0.5f. The default value 0.f.
