    \class QOpenGLFunctions
    \brief The QOpenGLFunctions class provides cross-platform access to the OpenGL ES 2.0 API.
    \since 5.0
    \ingroup painting-3D
    \inmodule QtGui

    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 MyGLWindow : public QWindow, protected QOpenGLFunctions
    {
        Q_OBJECT
    public:
        MyGLWindow(QScreen *screen = 0);

    protected:
        void initializeGL();
        void paintGL();

        QOpenGLContext *m_context;
    };

    MyGLWindow(QScreen *screen)
      : QWindow(screen), QOpenGLWidget(parent)
    {
        setSurfaceType(OpenGLSurface);
        create();

        // Create an OpenGL context
        m_context = new QOpenGLContext;
        m_context->create();

        // Setup scene and render it
        initializeGL();
        paintGL()
    }

    void MyGLWindow::initializeGL()
    {
        m_context->makeCurrent(this);
        initializeOpenGLFunctions();
    }
    \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 MyGLWindow::paintGL()
    {
        m_context->makeCurrent(this);
        glActiveTexture(GL_TEXTURE1);
        glBindTexture(GL_TEXTURE_2D, textureId);
        ...
        m_context->swapBuffers(this);
        m_context->doneCurrent();
    }
    \endcode

    QOpenGLFunctions can also be used directly for ad-hoc invocation
    of OpenGL ES 2.0 functions on all platforms:

    \code
    QOpenGLFunctions glFuncs(QOpenGLContext::currentContext());
    glFuncs.glActiveTexture(GL_TEXTURE1);
    \endcode

    An alternative approach is to query the context's associated
    QOpenGLFunctions instance. This is somewhat faster than the previous
    approach due to avoiding the creation of a new instance, but the difference
    is fairly small since the internal data structures are shared, and function
    resolving happens only once for a given context, regardless of the number of
    QOpenGLFunctions instances initialized for it.

    \code
    QOpenGLFunctions *glFuncs = QOpenGLContext::currentContext()->functions();
    glFuncs->glActiveTexture(GL_TEXTURE1);
    \endcode

    QOpenGLFunctions provides wrappers for all OpenGL ES 2.0
    functions, including the common subset of OpenGL 1.x and ES
    2.0. While such functions, for example glClear() or
    glDrawArrays(), can be called also directly, as long as the
    application links to the platform-specific OpenGL library, calling
    them via QOpenGLFunctions enables the possibility of dynamically
    loading the OpenGL implementation.

    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(QOpenGLContext::currentContext());
    bool npot = funcs.hasOpenGLFeature(QOpenGLFunctions::NPOTTextures);
    \endcode

    \sa QOpenGLContext, QSurfaceFormat

    \class QOpenGLExtraFunctions
    \brief The QOpenGLExtraFunctions class provides cross-platform access to the OpenGL ES 3.0 and 3.1 API.
    \since 5.6
    \ingroup painting-3D
    \inmodule QtGui

    This subclass of QOpenGLFunctions includes the OpenGL ES 3.0 and 3.1
    functions. These will only work when an OpenGL ES 3.0 or 3.1 context, or an
    OpenGL context of a version containing the functions in question either in
    core or as extension, is in use. This allows developing GLES 3.0 and 3.1
    applications in a cross-platform manner: development can happen on a desktop
    platform with OpenGL 3.x or 4.x, deploying to a real GLES 3.1 device later
    on will require no or minimal changes to the application.

    \note This class is different from the versioned OpenGL wrappers, for
    instance QOpenGLFunctions_3_2_Core. The versioned function wrappers target a
    given version and profile of OpenGL. They are therefore not suitable for
    cross-OpenGL-OpenGLES development.

    \fn void QOpenGLExtraFunctions::glVertexBindingDivisor(GLuint bindingindex, GLuint divisor)

    Convenience function that calls glVertexBindingDivisor(\a bindingindex, \a divisor).

    This function is only available in OpenGL ES 3.x, or OpenGL 3.x or 4.x contexts. When running
    with plain OpenGL, the function is only usable when the given profile and version contains the
    function either in core or as an extension.

    For more information, see the OpenGL ES 3.x documentation for
    \l{http://www.khronos.org/opengles/sdk/docs/man31/glVertexBindingDivisor.xml}{glVertexBindingDivisor()}.

// Functions part of the OpenGL ES 3.0+ standard need special handling. These, just like
// the 2.0 functions, are not guaranteed to be resolvable via eglGetProcAddress or
// similar. (we cannot count on EGL_KHR_(client_)get_all_proc_addresses being available)

// Calling them directly is, unlike the 2.0 functions, not feasible because one may build
// the binaries on a GLES3-capable system and then deploy on a GLES2-only system that does
// not have these symbols, and vice versa. Until ES3 becomes universally available, they
// have to be dlsym'ed.
