- Added PowerScaling to RenderableVolumeGL and RenderableFieldlines - Removed the use of volumeraycasterbox since it used FBO and textures which was not used anymore. - Added a simple box implementation to RenderableVolumeGL that can have PowerScaled vertex positions TODO: The #include command needs to be extended in some way since the FieldLines passthrough shader can't access the PowerScaled includes in a good way.
