DocBook: export the preview images to the right format.

Browse Source 
"docbook" is not the same as "docbook5", maybe it would be better to have an enumeration instead of strings.

<title>Linguistic structure trees</title>
<para>Here is a simple example:</para>
<mediaobject>
<imageobject>
<imagedata fileref='lyxpreviewAJskuj1.png' />
</imageobject>
<textobject>
<programlisting language='latex' role='forest'>[VP [DP[John]] [V' [V[sent]] [DP[Mary]] [DP[D[a]][NP[letter]]] ] ]</programlisting>
</textobject>
</mediaobject>
<para>If you view the PDF output, you will see that the input</para>
<blockquote>
<para><code><emphasis role='size_small'>[VP [DP[John]] [V' [V[sent]] [DP[Mary]] [DP[D[a]][NP[letter]]]]]</emphasis></code></para>
</blockquote>
<para>expands to a real structure tree. To view the result within the work area, you can simply embed the Structure Tree inset into a Preview inset. If instant preview is correctly installed and activated, you should see the tree immediately (just click on the image in order to edit):</para>
<para><mediaobject>
<imageobject>
<imagedata fileref='lyxpreviewWZhpAx1.png' />
</imageobject>
<textobject>
<programlisting language='latex' role='forest'>[VP [DP[Mary]] [V' [V[sent]] [DP[John]] [DP[D[a]][NP[response]]] ] ]</programlisting>
</textobject>
</mediaobject></para>
<para>Roofs can be easily generated by means of the <code>roof</code> option (note that the comma has special meaning, as it marks options):</para>
<mediaobject>
<imageobject>
<imagedata fileref='lyxpreviewQJTcYJ1.png' />
</imageobject>
<textobject>
<programlisting language='latex' role='forest'>[VP [DP[John]] [V' [V[sent]] [DP[Mary]] [DP[another letter, roof]] ] ]</programlisting>
</textobject>
</mediaobject>
<para>In order to align nodes of the tree more elegantly, use the &#8220;tier&#8221; option. All nodes which have the same <code>tier</code> allocated get aligned. Here is an example:</para>
<mediaobject>
<imageobject>
<imagedata fileref='lyxpreviewBkSuoA1.png' />
</imageobject>
<textobject>
<programlisting language='latex' role='forest'>[VP [DP[John,tier=word]] [V' [V[sent,tier=word]] [DP[Mary,tier=word]] [DP[D[a,tier=word]][NP[letter,tier=word]]] ] ]</programlisting>
</textobject>
</mediaobject>
<para>The package supports many additional features, such as movement arrows and decorations, that cannot documented here.</para>
