Inversely transforms (multiplies) the [AABB] by the given [Transform3D] transformation matrix.
Inversely transforms (multiplies) the [AABB] by the given [Transform3D] transformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).
[code]aabb * transform[/code] is equivalent to [code]transform.inverse() * aabb[/code]. See [method Transform3D.inverse].
For transforming by inverse of an affine transformation (e.g. with scaling) [code]transform.affine_inverse() * aabb[/code] can be used instead. See [method Transform3D.affine_inverse].
