[BREAKING] VolumeSceneLayerSource now locks the viewport properly before using the scene. The ctor now accepts the viewport instead of a ref. to the scene. RtViewer sample has been adapted accordingly.

| 35 This class applies one "volume slicer" to a "3D volume", in order | |
| 36 to create one "2D scene layer" that will be set onto the "2D | |
| 37 scene". The style of the layer can be fine-tuned using a "layer | |
| 38 style configurator". The class only changes the layer if the | |
| 39 cutting plane has been modified since the last call to "Update()". | |
