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.

Returns a copy of the transform rotated around the given [code]axis[/code] by the given [code]angle[/code] (in radians).
The [code]axis[/code] must be a normalized vector.
This method is an optimized version of multiplying the given transform [code]X[/code]
with a corresponding rotation transform [code]R[/code] from the left, i.e., [code]R * X[/code].
This can be seen as transforming with respect to the global/parent frame.
