/**
  Initializing an MDCBaseTextFieldLayout object with this initializer is tantamount to calculating a
  layout for a TextField. The admittedly long parameter list includes everything that might impact
  the layout of the textfield. Providing the object with everything that it needs to calculate a
  layout allows it to do so all in one place, in isolation, and in a top down fashion. The inability
  of other objects to interfere with this process helps ensure that the resulting layout is correct
  and reliable.
