Transform gizmo (dragger) used SoAnnotation which disables GL_DEPTH_TEST resulting in rendering elements in wrong order. This PR introduces new coin node: So3DAnnotation that delays rendering and clears depth buffer before drawing which results in proper order of elements. As this destroys information in the depth buffer it is crucial to run this action after the scene is rendered.
