SoComputeBoundingBox(3) on Linux
The text 7667abf883fa, as Debian 8 (Jessie) shipped it.
The SoComputeBoundingBox class is used to calculate a bounding box. This engine is simply a wrapper around the SoGetBoundingBoxAction, for a convenient way of having automatic updating of some data in the scene graph which is dependent on the bounding box of some other part of the scene.
