To better support sharing the functionality of slice rendering, the SliceExtractor processor was refactored: Similar to the RaycastingProcessor, the main functionality was moved to an abstract base class, the SliceRenderProcessor. This takes care of computing all the necessary transformation matrices, optionally rendering crosshair and integrating geometry, as well as handling user input to support scribbling. The actual SliceExtractor processor now only implements the rendering of the slice itself, i.e. applying the transfer function.

In this regard, VolumeExplorer was updated to use the generic SliceRenderProcessor, and TransFuncWindowingEventListener supports changing of its assigned property.
