master
Represents the master configuration of a font face.
This property encapsulates customizable variations of the font face, defined by its axes and ranges, which determine the adjustable properties of the font. It provides access to these variations in order to manipulate or query specific font characteristics.
Note: This property returns a mutable copy of this Face's master configuration. Changing the values in the returned master does not affect this Face instance. To create a new Face with modified master settings, use the returned master in combination with withMaster.
