GLES drivers adapted, but only did make compile-tests.

<p>Since version 1.1, Irrlicht is able to save and load the full scene
graph into an .irr file, an xml based format. There is also an editor
available to edit those files, named irrEdit on <a href="http://www.ambiera.com/irredit" target="_blank">http://www.ambiera.com/irredit</a>,
which can also be used as world and particle editor. This tutorial shows
how to use .irr files.</p>

<p>Now load our .irr file. .irr files can store the whole scene graph
including animators, materials and particle systems. And there is also
the possibility to store arbitrary user data for every scene node in
that file. To keep this example simple, we are simply loading the scene
here. See the documentation at ISceneManager::loadScene and ISceneManager::saveScene
for more information. So to load and display a complicated huge scene,
we only need a single call to loadScene().</p>

<p>That was it already. Now add a camera and draw the scene.</p>
