SoBoxHighlightRenderAction(3) on Linux
The text e9869a003e9b, as Debian 7 (Wheezy) shipped it.
The SoBoxHighlightRenderAction class renders the scene with highlighted boxes around selections. This action performs the same tasks as its parent class, SoGLRenderAction, with the added ability to render highlighted bounding boxes around geometry in selected nodes. This is a simple but convenient way of giving feedback to the user upon interaction with the scene graph.
