Selection highlight style.
SoLineHighlightRenderAction is a render action which renders the specified scene graph, then renders each selected object again in wireframe. Selected objects are specified by the first SoSelection node in the scene to which this action is applied. If there is no renderable geometry in a selected object, no highlight is rendered for that object. A highlight render action can be passed to the setGLRenderAction() method of SoQtRenderArea to have an affect on scene graphs.
