Axis Variations Table

This class represents the avar table of a variable font. The object has one substantive attribute, segments, which maps axis tags to a segments dictionary:

>>> font["avar"].segments   
{'wght': {-1.0: -1.0,
  0.0: 0.0,
  0.125: 0.11444091796875,
  0.25: 0.23492431640625,
  0.5: 0.35540771484375,
  0.625: 0.5,
  0.75: 0.6566162109375,
  0.875: 0.81927490234375,
  1.0: 1.0},
 'ital': {-1.0: -1.0, 0.0: 0.0, 1.0: 1.0}}

Notice that the segments dictionary is made up of normalized values. A valid avar segment mapping must contain the entries -1.0: -1.0, 0.0: 0.0, 1.0: 1.0. fontTools does not enforce this, so it is your responsibility to ensure that mappings are valid.
