Doc: Move literal code block to a separate file

We need to override this snippet for the documentation
we generate for Qt for Python, and it is easier to have
it on a separate file.

     direct inheritance:
 
-    \code
-    class MyGLWidget : public QGLWidget, protected QGLFunctions
-    {
-        Q_OBJECT
-    public:
-        MyGLWidget(QWidget *parent = 0) : QGLWidget(parent) {}

     The \c{paintGL()} function can then use any of the OpenGL ES 2.0
     functions without explicit resolution, such as glActiveTexture()
     in the following example:
 
-    \code
-    void MyGLWidget::paintGL()
-    {
-        glActiveTexture(GL_TEXTURE1);
-        glBindTexture(GL_TEXTURE_2D, textureId);
-        ...
-    }
-    \endcode

     QGLFunctions can also be used directly for ad-hoc invocation
     of OpenGL ES 2.0 functions on all platforms:
 
-    \code
-    QGLFunctions glFuncs(QGLContext::currentContext());
-    glFuncs.glActiveTexture(GL_TEXTURE1);
-    \endcode

     textures are available:
