docs: explain that layout height/width must be used to override include layouts

         layout=”@layout/title”/>

</pre>

<p>However, if you want to override layout attributes using

the <code>&lt;include&gt;</code> tag, you must override both

<code>android:layout_height</code> and <code>android:layout_width</code> in order for

other layout attributes to take effect.</p>
