docs: Replies the sensibility of the panning moves after applying dynamic user interaction modifiers.
  The sensibility is a strictly positive number that is multiplied to the
  distance covered by the mouse motion for obtaining the move to
  apply to the document.
  The default value is 1.
  
  <p>This function is usually used for computing the sensibility within mouse handlers.
  The Shift and Control key flags may be used as the modifiers.
  
  <p>If {@code unitSensitivityModifier} is {@code true}, the sensibility is always {@code 1}.
  If {@code hugeSensivityModifier} is {@code true}, the sensibility is multiplied by {@link #LARGE_MOVE_FACTOR}.
  Otherwise, the value returned by {@link #getPanSensitivity()} is returned.
  
  @param unitSensitivityModifier the user chooses the unit sensitivity dynamically. If {@code true}, this
  parameter has precedence to the other parameters.
  @param hugeSensivityModifier the user chooses a huge sensitivity dynamically.
  @return the sensitivity.
