/**
* RectangleROIAnnotation let you draw annotations that measures the statistics
* such as area, max, mean and stdDev of a Rectangular region of interest.
* You can use RectangleROIAnnotation in all perpendicular views (axial, sagittal, coronal).
* Note: annotation tools in cornerstone3DTools exists in the exact location
* in the physical 3d space, as a result, by default, all annotations that are
* drawing in the same frameOfReference will get shared between viewports that
* are in the same frameOfReference. RectangleROI tool's text box lines are dynamically
* generated based on the viewport's underlying Modality. For instance, if
* the viewport is displaying CT, the text box will shown the statistics in Hounsfield units,
* and if the viewport is displaying PET, the text box will show the statistics in
* SUV units.
*
* The resulting annotation's data (statistics) and metadata (the
* state of the viewport while drawing was happening) will get added to the
* ToolState manager and can be accessed from the ToolState by calling getAnnotations
* or similar methods.
*
* ```js
* cornerstoneTools.addTool(RectangleROITool)
*
* const toolGroup = ToolGroupManager.createToolGroup('toolGroupId')
*
* toolGroup.addTool(RectangleROITool.toolName)
*
* toolGroup.addViewport('viewportId', 'renderingEngineId')
*
* toolGroup.setToolActive(RectangleROITool.toolName, {
* bindings: [
* {
* mouseButton: MouseBindings.Primary, // Left Click
* },
* ],
* })
* ```
