    Access Stats and Color Range for a Stretch Renderer
    //var voxelLayer = ... ;
    //Must be on the QueuedTask.Run()
    //Get the variable profile on which to access the data
    var variable = voxelLayer.SelectedVariableProfile;
    //or use ...voxelLayer.GetVariableProfiles()
    //Data range
    //At 2.x - 
    //var min = variable.GetVariableStatistics().MinimumValue;
    //var max = variable.GetVariableStatistics().MaximumValue;

    Change Stretch Renderer Color Range
    //Typically, the default color range covers the most
    //commonly occuring voxel values. Usually, the data
    //range is much broader than the color range
