    \class QAbstractOpenGLFunctions
    \inmodule QtGui
    \since 5.1
    \brief The QAbstractOpenGLFunctions class is the base class of a family of
           classes that expose all functions for each OpenGL version and
           profile.

    OpenGL implementations on different platforms are able to link to a variable
    number of OpenGL functions depending upon the OpenGL ABI on that platform.
    For example, on Microsoft Windows only functions up to those in OpenGL 1.1
    can be linked to at build time. All other functions must be resolved at
    runtime. The traditional solution to this has been to use either
    QOpenGLContext::getProcAddress() or QOpenGLFunctions. The former is tedious
    and error prone and means dealing directly with function pointers. The
    latter only exposes those functions common to OpenGL ES 2 and desktop
    OpenGL. There is however much new OpenGL functionality that is useful when
    writing real world OpenGL applications.

    Qt now provides a family of classes which all inherit from
    QAbstractOpenGLFunctions which expose every core OpenGL function by way of a
    corresponding member function. There is a class for every valid combination
    of OpenGL version and profile. Each class follows the naming convention
    QOpenGLFunctions_<MAJOR VERSION>_<MINOR VERSION>[_PROFILE].

    For OpenGL versions 1.0 through to 3.0 there are no profiles, leading to the
    classes:

    \list
        \li QOpenGLFunctions_1_0
        \li QOpenGLFunctions_1_1
        \li QOpenGLFunctions_1_2
        \li QOpenGLFunctions_1_3
        \li QOpenGLFunctions_1_4
        \li QOpenGLFunctions_1_5
        \li QOpenGLFunctions_2_0
        \li QOpenGLFunctions_2_1
        \li QOpenGLFunctions_3_0
    \endlist

    where each class inherits from QAbstractOpenGLFunctions.

    OpenGL version 3.1 removed many deprecated functions leading to a much
    simpler and generic API.

    With OpenGL 3.2 the concept of profiles was introduced. Two profiles are
    currently defined for OpenGL: Core and Compatibility.

    The Core profile does not include any of the functions that were removed
    in OpenGL 3.1. The Compatibility profile contains all functions in the
    Core profile of the same version plus all of the functions that were
    removed in OpenGL 3.1. In this way the Compatibility profile classes allow
    use of newer OpenGL functionality but also allows you to keep using your
    legacy OpenGL code. For new OpenGL code the Core profile should be
    preferred.

    Please note that some vendors, notably Apple, do not implement the
    Compatibility profile. Therefore if you wish to target new OpenGL features
    on OS X then you should ensure that you request a Core profile context via
    QSurfaceFormat::setProfile().

    Qt provides classes for all version and Core and Compatibility profile
    combinations. The classes for OpenGL versions 3.1 through to 4.3 are:

    \list
        \li QOpenGLFunctions_3_1
        \li QOpenGLFunctions_3_2_Core
        \li QOpenGLFunctions_3_2_Compatibility
        \li QOpenGLFunctions_3_3_Core
        \li QOpenGLFunctions_3_3_Compatibility
        \li QOpenGLFunctions_4_0_Core
        \li QOpenGLFunctions_4_0_Compatibility
        \li QOpenGLFunctions_4_1_Core
        \li QOpenGLFunctions_4_1_Compatibility
        \li QOpenGLFunctions_4_2_Core
        \li QOpenGLFunctions_4_2_Compatibility
        \li QOpenGLFunctions_4_3_Core
        \li QOpenGLFunctions_4_3_Compatibility
    \endlist

    where each class inherits from QAbstractOpenGLFunctions.

    A pointer to an object of the class corresponding to the version and
    profile of OpenGL in use can be obtained from
    QOpenGLFunctions::versionFunctions(). If obtained in this way, note that
    the QOpenGLContext retains ownership of the object. This is so that only
    one instance need be created.

    Before calling any of the exposed OpenGL functions you must ensure that the
    object has resolved the function pointers to the OpenGL functions. This
    only needs to be done once per instance with initializeOpenGLFunctions().
    Once initialized, the object can be used to call any OpenGL function for
    the corresponding version and profile. Note that initializeOpenGLFunctions()
    can fail in some circumstances so check the return value. Situations in
    which initialization can fail are if you have a functions object for a version
    or profile that contains functions that are not part of the context being
    used to resolve the function pointers.

    If you exclusively use function objects then you will get compile time
    errors if you attempt to use a function not included in that version and
    profile. This is obviously a lot easier to debug than undefined behavior
    at run time.
