title: How to change hint's fontSize' of TextInputLayout widget?
body: <p>I have a such TextInputLayout widget on my screen</p>
  
  <pre><code>&lt;android.support.design.widget.TextInputLayout
          android:id="@+id/editTextClient"
          android:textColorHint="@color/colorPrimaryText"
          app:errorEnabled="true"
          app:hintEnabled="true"
          android:hint="@string/login"
          app:errorTextAppearance="@style/ErrorAppearence"
          app:hintTextAppearance="@style/TextLabel"&gt;
  
      &lt;android.support.design.widget.TextInputEditText
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:inputType="text"
              android:singleLine="true"
              android:textColor="@color/colorPrimaryText"/&gt;
  &lt;/android.support.design.widget.TextInputLayout&gt;
  </code></pre>
  
  <p>The style @style/ErrorAppearence defines error message. The style @style/TextLabel defines active label, when we'are printing something.</p>
  
  <pre><code>&lt;style name="TextLabel" parent="TextAppearance.Design.Hint"&gt;
      &lt;item name="android:textColor"&gt;@color/colorPrimaryText&lt;/item&gt;
      &lt;item name="android:textSize"&gt;12sp&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="ErrorAppearence"&gt;
      &lt;item name="android:textColor"&gt;@color/colorAccent&lt;/item&gt;
      &lt;item name="android:textSize"&gt;12sp&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Now I want to lower fontSize of EditText label, when it's not in active state. I need your help here, because I don't know what attribute I must tweak to achieve this. To define clearly what I'm meaning by "Label" I've attached picture below
