Public Member Functions
	KhrTextureTransform () noexcept
	Constructs a texture transformation with identity values.
	KhrTextureTransform (const ExtensionKhrTextureTransform &extension) noexcept
	Constructs a texture transformation from the given extension.
KhrTextureTransformStatus	status () const noexcept
	The current KhrTextureTransformStatus of the transform operation.
glm::dvec2	offset () const noexcept
	Gets the offset of the texture transform.
double	rotation () const noexcept
	Gets the rotation (in radians) of the texture transform.
glm::dvec2	rotationSineCosine () const noexcept
	Gets the sine and cosine of the rotation in the texture transform. This is cached to avoid re-computing the values in the future.
glm::dvec2	scale () const noexcept
	Gets the scale of the texture transform.
glm::dvec2	applyTransform (double u, double v) const noexcept
	Applies this texture transformation to the input coordinates.
std::optional< int64_t >	getTexCoordSetIndex () const noexcept
	Gets the texture coordinate set index used by this texture transform. If defined, this should override the set index of the texture's original textureInfo.
