Summary

Public constructors
`MetricAffectingSpan()`

Public methods
open MetricAffectingSpan!	`getUnderlying()` Returns "this" for most MetricAffectingSpans, but for MetricAffectingSpans that were generated by `wrap`, returns the underlying MetricAffectingSpan.
abstract Unit	`updateMeasureState(textPaint: TextPaint)` Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.
