You can use instances of this class to either configure the scale factor or the tracking adjustements used when drawing an attributed string.
You can set the properties up front with the NSStringDrawingContext.MinimumScaleFactor and NSStringDrawingContext.MinimumTrackingAdjustment.
After drawing you can examine the actual values used by examining the NSStringDrawingContext.ActualScaleFactor and NSStringDrawingContext.ActualTrackingAdjustment properties.
