/**
* In Cornerstone3DTools, displaying of segmentations are handled by the SegmentationDisplayTool.
* Generally, any Segmentation can be viewed in various representations such as
* labelmap (3d), contours, surface etc. As of now, Cornerstone3DTools only implements
* Labelmap representation.
*
* SegmentationDisplayTool works at ToolGroup level, and is responsible for displaying the
* segmentation representation for ALL viewports of a toolGroup, this way we can support complex
* scenarios for displaying segmentations.
*
* Current Limitations:
* - Only supports rendering of the volumetric segmentations in 3D space. (StackViewport segmentations are not supported yet)
* - Labelmap representation is the only supported representation for now.
*
* Similar to other tools in Cornerstone3DTools, the SegmentationDisplayTool should
* be added to the CornerstoneTools by calling cornerstoneTools.addTool(SegmentationDisplayTool)
* and a toolGroup should be created for it using the ToolGroupManager API, finally
* viewports information such as viewportId and renderingEngineId should be provided
* to the toolGroup and the SegmentationDisplayTool should be set to be activated.
