		3D transformation (3×4 matrix).
	</brief_description>
	<description>
		3×4 matrix (3 rows, 4 columns) used for 3D linear transformations. It can represent transformations such as translation, rotation, or scaling. It consists of a [member basis] (first 3 columns) and a [Vector3] for the [member origin] (last column).
		For more information, read the "Matrices and transforms" documentation article.

			<description>
				Returns the inverse of the transform, under the assumption that the transformation is composed of rotation and translation (no scaling, use affine_inverse for transforms with scaling).

			<description>
				Returns a copy of the transform rotated such that its -Z axis points towards the [code]target[/code] position.
				The transform will first be rotated around the given [code]up[/code] vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the [code]target[/code] and [code]up[/code] vectors.
