Add files ported from research/qt3d

Fill repo with some of the files from the research/qt3d project.  At
present the new project builds under MacOSX.  To-dos include getting it
building under linux, windows, harmattan and maemo/meego; updating the
documentation to reflect the new QtQuick focus; and fixing the issues
with private headers.

+/*!
+    \class QOpenGLFunctions
+    \brief The QOpenGLFunctions class provides cross-platform access to the OpenGL/ES 2.0 API.
+    \since 4.8
+    \ingroup qt3d
+    \ingroup qt3d::enablers
+
+    OpenGL/ES 2.0 defines a subset of the OpenGL specification that is
+    common across many desktop and embedded OpenGL implementations.
+    However, it can be difficult to use the functions from that subset
+    because they need to be resolved manually on desktop systems.
+
+    QOpenGLFunctions provides a guaranteed API that is available on all
+    OpenGL systems and takes care of function resolution on systems
+    that need it.  The recommended way to use QOpenGLFunctions is by
+    direct inheritance:
+
+    \code
+    class MyGLWidget : public QGLWidget, protected QOpenGLFunctions
+    {
+        Q_OBJECT
+    public:
+        MyGLWidget(QWidget *parent = 0) : QGLWidget(parent) {}
+
+    protected:
+        void initializeGL();
+        void paintGL();
+    };
+
+    void MyGLWidget::initializeGL()
+    {
+        initializeGLFunctions();
+    }
+    \endcode
+
+    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
+
+    QOpenGLFunctions can also be used directly for ad-hoc invocation
+    of OpenGL/ES 2.0 functions on all platforms:
+
+    \code
+    QOpenGLFunctions glFuncs(QGLContext::currentContext());
+    glFuncs.glActiveTexture(GL_TEXTURE1);
+    \endcode
+
+    QOpenGLFunctions provides wrappers for all OpenGL/ES 2.0 functions,
+    except those like \c{glDrawArrays()}, \c{glViewport()}, and
+    \c{glBindTexture()} that don't have portability issues.
+
+    Including the header for QOpenGLFunctions will also define all of
+    the OpenGL/ES 2.0 macro constants that are not already defined by
+    the system's OpenGL headers, such as \c{GL_TEXTURE1} above.
+
+    The hasOpenGLFeature() and openGLFeatures() functions can be used
+    to determine if the OpenGL implementation has a major OpenGL/ES 2.0
+    feature.  For example, the following checks if non power of two
+    textures are available:
+
+    \code
+    QOpenGLFunctions funcs(QGLContext::currentContext());
+    bool npot = funcs.hasOpenGLFeature(QOpenGLFunctions::NPOTTextures);
+    \endcode
+*/
+
+/*!
