+
+    Disconnects \a signal in object \a sender from \a method in object
+    \a receiver. Returns true if the connection is successfully broken;
+    otherwise returns false.
+
+    This function provides the same posibilities like
+    disconnect(const QObject *sender, const char *signal, const QObject *receiver, const char *method)
+    but uses QMetaMethod to represent the signal and the method to be disconnected.
+
+    Additionally this function returnsfalse and no signals and slots disconnected
+    if:
+    \list 1
+
+        \i \a signal is not a member of sender class or one of its parent classes.
+
+        \i \a method is not a member of receiver class or one of its parent classes.
+
+        \i \a signal instance represents not a signal.
+
+    \endlist
+
+    QMetaMethod() may be used as wildcard in the meaning "any signal" or "any slot in receiving object".
+    In the same way 0 can be used for \a receiver in the meaning "any receiving object". In this case
+    method shoud also be QMetaMethod(). \a sender parameter should be never 0.

-    A function pointer type. Use a function with this prototype to install
-    interface factories with installFactory().
+    This is a typedef for a pointer to a function with the following
+    signature:
 
-    The function receives a QObject pointer. If the QObject
-    provides a QAccessibleInterface, it sets the second parameter to
-    point to the corresponding QAccessibleInterface, and returns true;
-    otherwise returns false.
+    \snippet doc/src/snippets/code/src_gui_accessible_qaccessible.cpp 1
+
+    The function receives a QString and a QObject pointer, where the
+    QString is the key identifying the interface. The QObject is used
+    to pass on to the QAccessibleInterface so that it can hold a reference
+    to it.
+
+    If the key and the QObject does not have a corresponding
+    QAccessibleInterface, a null-pointer will be returned.
 
     Installed factories are called by queryAccessibilityInterface() until
     one provides an interface.

+    \brief The QPlatformGLContext class provides an abstraction for native GL contexts.
+
+    In QPA the way to support OpenGL or OpenVG or other technologies that requires a native GL
+    context is through the QPlatformGLContext wrapper.
+
+    There is no factory function for QPlatformGLContexts, but rather only one accessor function.
+    The only place to retrieve a QPlatformGLContext from is through a QPlatformWindow.
+
+    The context which is current for a specific thread can be collected by the currentContext()
+    function. This is how QPlatformGLContext also makes it possible to use the QtOpenGL module
+    withhout using QGLWidget. When using QGLContext::currentContext(), it will ask
+    QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned,
+    which maps to the QPlatformGLContext.

+*/
+
+/*! platformWindowFormat() const
+    QWidget has the function qplatformWindowFormat(). That function is for the application
+    programmer to request the format of the window and the context that he wants.
+
+    Reimplement this function in a subclass to indicate what format the glContext actually has.

+
+    QPlatformIntegration is the single entry point for windowsystem specific functionality when

+    windows. The class also controls the font subsystem.
+
+    QPlatformIntegration is a singelton class which gets instansiated in the QApplication
+    constructor. The QPlatformIntegration instance do not have ownership of objects it creates in
+    functions where the name starts with create. However, functions which don't have a name
+    starting with create acts as assessors to member variables.
+
+    It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefor
+    the recommended approach for making new platform plugin is to copy an existing plugin inside
+    the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree.
+
+    The minimal platformintegration is the smallest platform integration it is possible to make,
+    which makes it an ideal starting point for new plugins. For a slightly more advanced plugin,
+    consider reviewing the directfb plugin, or the testlite plugin.

+    instance.
+
+    QPlatformWindow is used to signal to the windowing system, how Qt persieves its frame.

+
+    Top level QWidgets(tlw) will always have a QPlatformWindow. However, it is not necessary for
+    all tlw to have a QWindowSurface. This is the case for QGLWidget. And could be the case for
+    widgets where some  3.party renders into it.
+
+    The platform specific window handle can be retrieved by the winId function.
+
+    QPlatformWindow is also the way QPA defines how native child windows should be supported
+    through the setParent function.
+
+    The only way to retrieve a QPlatformGLContext in QPA is by calling the glContext() function
+    on QPlatformWindow.

+    You can also specify preferred bit depths for the color buffer,
+    depth buffer, alpha buffer, accumulation buffer and the stencil
+    buffer with the functions: setRedBufferSize(), setGreenBufferSize(),
+    setBlueBufferSize(), setDepthBufferSize(), setAlphaBufferSize(),
+    setAccumBufferSize() and setStencilBufferSize().
+
+    Note that even if you specify that you prefer a 32 bit depth
+    buffer (e.g. with setDepthBufferSize(32)), the format that is
+    chosen may not have a 32 bit depth buffer, even if there is a
+    format available with a 32 bit depth buffer. The main reason for
+    this is how the system dependant picking algorithms work on the
+    different platforms, and some format options may have higher
+    precedence than others.
+
+    You create and tell a QPlatformWindowFormat object what rendering options you
+    want from an OpenGL rendering context.
+
+    OpenGL drivers or accelerated hardware may or may not support
+    advanced features such as alpha channel or stereographic viewing.
+    If you request some features that the driver/hardware does not
+    provide when you create a QGLWidget, you will get a rendering
+    context with the nearest subset of features.
+
+    There are different ways to define the display characteristics of
+    a rendering context. One is to create a QPlatformWindowFormat and make it the
+    default for the entire application:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 0
+
+    Or you can specify the desired format when creating an object of
+    your QGLWidget subclass:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 1
+
+    After the widget has been created, you can find out which of the
+    requested features the system was able to provide:

+/*!
+    \class QGlyphs
+    \brief the QGlyphs class provides direct access to the internal glyphs in a font
+    \since 4.8
+
+    \ingroup text
+    \mainclass
+
+    When Qt displays a string of text encoded in Unicode, it will first convert the Unicode points
+    into a list of glyph indexes and a list of positions based on one or more fonts. The Unicode
+    representation of the text and the QFont object will in this case serve as a convenient
+    abstraction that hides the details of what actually takes place when displaying the text
+    on-screen. For instance, by the time the text actually reaches the screen, it may be represented
+    by a set of fonts in addition to the one specified by the user, e.g. in case the originally
+    selected font did not support all the writing systems contained in the text.
+
+    Under certain circumstances, it can be useful as an application developer to have more low-level
+    control over which glyphs in a specific font are drawn to the screen. This could for instance
+    be the case in applications that use an external font engine and text shaper together with Qt.
+    QGlyphs provides an interface to the raw data needed to get text on the screen. It
+    contains a list of glyph indexes, a position for each glyph and a font.
+
+    It is the user's responsibility to ensure that the selected font actually contains the
+    provided glyph indexes.
+
+    QTextLayout::glyphs() can be used to convert unicode encoded text into a list of QGlyphs
+    objects, and QPainter::drawGlyphs() can be used to draw the glyphs.

+    and how they are rendered
+
+    \ingroup painting
+
+    QPlatformFontDatabase is the superclass which is intended to let platform implementations use
+    native font handling.
+
+    Qt has its internal fontdatabase which it uses to pick up available fonts. To be able
+    to populate this database subclass this class, and reimplement populateFontDatabase().
+
+    Use the function registerFont to populate the internal fontdatabase.
+
+    Sometimes a specified font does not have the required glyphs, then the fallbackForFamily
+    function is called.

+    \class QScroller
+    \brief The QScroller class enables kinetic scrolling for any scrolling widget or graphics item.
+    \since 4.8
+
+    With kinetic scrolling, the user can push the widget in a given
+    direction and it will continue to scroll in this direction until it is
+    stopped either by the user or by friction.  Aspects of inertia, friction
+    and other physical concepts can be changed in order to fine-tune an
+    intuitive user experience.
+
+    The QScroller object is the object that stores the current position and
+    speed of the scrolling and takes care of updates.
+    QScroller can be triggered by a flick gesture
+
+    \code
+        QWidget *w = ...;
+        QScroller::grabGesture(w, QScroller::LeftMouseButtonGesture);
+    \endcode
+
+    or directly like this:
+
+    \code
+        QWidget *w = ...;
+        QScroller *scroller = QScroller::scroller(w);
+        scroller->scrollTo(QPointF(100, 100));
+    \endcode
+
+    The scrolled QObjects will be receive a QScrollPrepareEvent whenever the scroller needs to
+    update its geometry information and a QScrollEvent whenever the content of the object should
+    actually be scrolled.
+
+    The scroller uses the global QAbstractAnimation timer to generate its QScrollEvents, but this
+    can be slowed down with QScrollerProperties::FrameRate on a per-QScroller basis.
+
+    Several examples in the \c scroller examples directory show how QScroller,
+    QScrollEvent and the scroller gesture can be used.
+
+    Even though this kinetic scroller has a huge number of settings available via
+    QScrollerProperties, we recommend that you leave them all at their default, platform optimized
+    values. In case you really want to change them you can experiment with the \c plot example in
+    the \c scroller examples directory first.

+    \value OvershootAlwaysOff Overshooting is never enabled (even when the content is scrollable).
+
+    \value OvershootAlwaysOn Overshooting is always enabled (even when the content is not
+                             scrollable).
+*/
+
+/*!
+    \enum QScrollerProperties::ScrollMetric
+
+    This enum contains the different scroll metric types. When not indicated otherwise the
+    setScrollMetric function expects a QVariant of a real value.
+
+    See the QScroller documentation for a further explanation of the concepts behind the different
+    values.
+
+    \value MousePressEventDelay This is the time a mouse press event will be delayed when starting
+    a flick gesture in \c{[s]}. If the gesture is triggered within that time, no mouse press or
+    release will be sent to the scrolled object. If it triggers after that delay the (delayed)
+    mouse press plus a faked release event (at global postion \c{QPoint(-QWIDGETSIZE_MAX,
+    -QWIDGETSIZE_MAX)} will be sent. If the gesture is canceled, then both the (delayed) mouse
+    press plus the real release event will be delivered.
+
+    \value DragStartDistance This is the minimum distance the touch or mouse point needs to be
+    moved before the flick gesture is triggered in \c m.
+
+    \value DragVelocitySmoothingFactor A value that describes how much new drag velocities are
+    included in the final scrolling velocity.  This value should be in the range between \c 0 and
+    \c 1.  The lower the value, the more smoothing will be applied to the dragging velocity.  The
+    default value is \c 0.8.
+
+    \value AxisLockThreshold If greater than zero a scroll movement will be restricted to one axis
+    only if the movement is inside an angle about the axis. The threshold must be in the range \c 0
+    to \c 1.
+
+    \value ScrollingCurve The QEasingCurve used when decelerating the scrolling velocity after an
+    user initiated flick. Please note that this is the easing curve for the positions, \bold{not}
+    the velocity: the default is QEasingCurve::OutQuad, which results is a linear decrease in
+    velocity (1st derivative) and a constant deceleration (2nd derivative).
+
+    \value DecelerationFactor This factor influences how long it takes the scroller to decelerate
+    to 0 velocity. The actual value heavily depends on the chosen ScrollingCurve, but for most
+    types the value should be in the range from \c 0.1 to \c 2.0
+
+    \value MinimumVelocity The minimum velocity that is needed after ending the touch or releasing
+    the mouse to start scrolling in \c{m/s}.
+
+    \value MaximumVelocity This is the maximum velocity that can be reached in \c{m/s}.
+
+    \value MaximumClickThroughVelocity This is the maximum allowed scroll speed for a click-through
+    in \c{m/s}. This means that a click on a currently (slowly) scrolling object will not only stop
+    the scrolling but the click event will also be delivered to the UI control - this is very
+    useful when using exponential-type scrolling curves.
+
+    \value AcceleratingFlickMaximumTime This is the maximum time in \c seconds that a flick gesture
+    can take to be recognized as an accelerating flick. If set to zero no such gesture will be
+    detected. An "accelerating flick" is a flick gesture executed on an already scrolling object.
+    In such cases the scrolling speed is multiplied by AcceleratingFlickSpeedupFactor in order to
+    accelerate it.
+
+    \value AcceleratingFlickSpeedupFactor The current speed will be multiplied by this number if an
+    accelerating flick is detected. Should be \c{> 1}.
+
+    \value SnapPositionRatio This is the distance that the user must drag the area beween two snap
+    points in order to snap it to the next position. e.g. \c{0.33} means that the scroll must only
+    reach one third of the distance between two snap points to snap to the next one. The ratio must
+    be in the range \c 0 to \c 1.
+
+    \value SnapTime This is the time factor for the scrolling curve. A lower value means that the
+    scrolling will take longer. The scrolling distance is independet of this value.
+
+    \value OvershootDragResistanceFactor This value is the factor between the mouse dragging and
+    the actual scroll area movement (during overshoot). The factor must be in the range \c 0 to \c
+    1.
+
+    \value OvershootDragDistanceFactor This is the maximum distance for overshoot movements while
+    dragging. The actual overshoot distance will be calculated by multiplying this value with the
+    viewport size of the scrolled object. The factor must be in the range \c 0 to \c 1.
+
+    \value OvershootScrollDistanceFactor This is the maximum distance for overshoot movements while
+    scrolling. The actual overshoot distance will be calculated by multiplying this value with the
+    viewport size of the scrolled object. The factor must be in the range \c 0 to \c 1.
+
+    \value OvershootScrollTime This is the time in \c seconds that will be used to play the
+    complete overshoot animation.
+
+    \value HorizontalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
+
+    \value VerticalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
+
+    \value FrameRate This is the frame rate which should be used while dragging or scrolling.
+    QScroller uses a QAbstractAnimation timer internally to sync all scrolling operations to other
+    animations that might be active at the same time.  If the Standard value of 60 frames per
+    second is too fast for your use case, you can lower the frames per second with this setting
+    (while still being in-sync with QAbstractAnimation).  Please note that only the values of the
+    FrameRates enum are allowed here.
+
+    \value ScrollMetricCount This is just used when enumerating the metrics. It is always the last
+    entry.

+    QUdpSocket also supports UDP multicast. Use joinMulticastGroup() and
+    leaveMulticastGroup() to control group membership, and
+    QAbstractSocket::MulticastTtlOption and
+    QAbstractSocket::MulticastLoopbackOption to set the TTL and loopback socket
+    options. Use setMulticastInterface() to control the outgoing interface for
+    multicast datagrams, and multicastInterface() to query it.
+
     With QUdpSocket, you can also establish a virtual connection to a
     UDP server using connectToHost() and then use read() and write()
     to exchange datagrams without specifying the receiver for each
     datagram.
 
-    The \l{network/broadcastsender}{Broadcast Sender} and

+/*
+    This cache stores internal Qt shader programs in shared memory.
+
+    This header file is ugly on purpose and can only be included once. It is only to be used
+    for the internal shader cache, not as a generic cache for anyone's shaders.
+
+    The cache stores either ShaderCacheMaxEntries shader programs or ShaderCacheDataSize kilobytes
+    of shader programs, whatever limit is reached first.
+
+    The layout of the cache is as outlined in the CachedShaders struct. After some
+    integers, an array of headers is reserved, then comes the space for the actual binaries.
+
+    Shader Programs are identified by the md5sum of their frag and vertex shader source code.
+
+    Shader Programs are never removed. The cache never shrinks or re-shuffles. This is done
+    on purpose to ensure minimum amount of locking, no alignment problems and very few write
+    operations.
+
+    Note: Locking the shader cache could be expensive, because the entire system might hang.
+    That's why the cache is immutable to minimize the time we need to keep it locked.
+
+    Why is it Meego specific?
+
+    First, the size is chosen so that it fits to generic meego usage. Second, on Meego, there's
+    always at least one Qt application active (the launcher), so the cache will never be destroyed.
+    Only when the last Qt app exits, the cache dies, which should only be when someone kills the
+    X11 server. And last but not least it was only tested with Meego's SGX driver.
+
+    There's a small tool in src/opengl/util/meego that dumps the contents of the cache.

     \section1 Threading
 
-    It is possible to render into a QGLWidget from another thread, but it
-    requires that all access to the GL context is safe guarded. The Qt GUI
-    thread will try to use the context in resizeEvent and paintEvent, so in
-    order for threaded rendering using a GL widget to work, these functions
-    need to be intercepted in the GUI thread and handled accordingly in the
-    application.
+    As of Qt version 4.8, support for doing threaded GL rendering has
+    been improved. There are three scenarios that we currently support:
+    \list
+    \o 1. Buffer swapping in a thread.
+
+    Swapping buffers in a double buffered context may be a
+    synchronous, locking call that may be a costly operation in some
+    GL implementations. Especially so on embedded devices. It's not
+    optimal to have the CPU idling while the GPU is doing a buffer
+    swap. In those cases it is possible to do the rendering in the
+    main thread and do the actual buffer swap in a separate
+    thread. This can be done with the following steps:
+
+    1. Call doneCurrent() in the main thread when the rendering is
+    finished.
+
+    2. Notify the swapping thread that it can grab the context.
+
+    3. Make the rendering context current in the swapping thread with
+    makeCurrent() and then call swapBuffers().
+
+    4. Call doneCurrent() in the swapping thread and notify the main
+    thread that swapping is done.
+
+    Doing this will free up the main thread so that it can continue
+    with, for example, handling UI events or network requests. Even if
+    there is a context swap involved, it may be preferable compared to
+    having the main thread wait while the GPU finishes the swap
+    operation. Note that this is highly implementation dependent.
+
+    \o 2. Texture uploading in a thread.
+
+    Doing texture uploads in a thread may be very useful for
+    applications handling large amounts of images that needs to be
+    displayed, like for instance a photo gallery application. This is
+    supported in Qt through the existing bindTexture() API. A simple
+    way of doing this is to create two sharing QGLWidgets. One is made
+    current in the main GUI thread, while the other is made current in
+    the texture upload thread. The widget in the uploading thread is
+    never shown, it is only used for sharing textures with the main
+    thread. For each texture that is bound via bindTexture(), notify
+    the main thread so that it can start using the texture.
+
+    \o 3. Using QPainter to draw into a QGLWidget in a thread.
+
+    In Qt 4.8, it is possible to draw into a QGLWidget using a
+    QPainter in a separate thread. Note that this is also possible for
+    QGLPixelBuffers and QGLFramebufferObjects. Since this is only
+    supported in the GL 2 paint engine, OpenGL 2.0 or OpenGL ES 2.0 is
+    required.
+
+    QGLWidgets can only be created in the main GUI thread. This means
+    a call to doneCurrent() is necessary to release the GL context
+    from the main thread, before the widget can be drawn into by
+    another thread. Also, the main GUI thread will dispatch resize and
+    paint events to a QGLWidget when the widget is resized, or parts
+    of it becomes exposed or needs redrawing. It is therefore
+    necessary to handle those events because the default
+    implementations inside QGLWidget will try to make the QGLWidget's
+    context current, which again will interfere with any threads
+    rendering into the widget. Reimplement QGLWidget::paintEvent() and
+    QGLWidget::resizeEvent() to notify the rendering thread that a
+    resize or update is necessary, and be careful not to call the base
+    class implementation. If you are rendering an animation, it might
+    not be necessary to handle the paint event at all since the
+    rendering thread is doing regular updates. Then it would be enough
+    to reimplement QGLWidget::paintEvent() to do nothing.
+
+    \endlist
+
+    As a general rule when doing threaded rendering: be aware that
+    binding and releasing contexts in different threads have to be
+    synchronized by the user. A GL rendering context can only be
+    current in one thread at any time. If you try to open a QPainter
+    on a QGLWidget and the widget's rendering context is current in
+    another thread, it will fail.
+
+    Note that under X11 it is necessary to set the
+    Qt::AA_X11InitThreads application attribute to make the X11
+    library and GLX calls thread safe, otherwise the above scenarios
+    will fail.
+
+    In addition to this, rendering using raw GL calls in a separate
+    thread is supported.

+/*!
+    \class QGLFunctions
+    \brief The QGLFunctions class provides cross-platform access to the OpenGL/ES 2.0 API.
+    \since 4.8
+    \ingroup painting-3D
+
+    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.
+
+    QGLFunctions 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 QGLFunctions is by
+    direct inheritance:
+
+    \code
+    class MyGLWidget : public QGLWidget, protected QGLFunctions
+    {
+        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
+
+    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
+
+    QGLFunctions 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 QGLFunctions 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
+    QGLFunctions funcs(QGLContext::currentContext());
+    bool npot = funcs.hasOpenGLFeature(QGLFunctions::NPOTTextures);
+    \endcode
+*/
+
+/*!

+    As of Qt 4.8, it's possible to render into a QGLPixelBuffer using
+    a QPainter in a separate thread. Note that OpenGL 2.0 or OpenGL ES
+    2.0 is required for this to work. Also, under X11, it's necessary
+    to set the Qt::AA_X11InitThreads application attribute.
+
     Pbuffers are provided by the OpenGL \c pbuffer extension; call
     hasOpenGLPbuffer() to find out if the system provides pbuffers.

+EGL NullWS QScreen Driver
+=========================
+
+If your application draws everything within a single full-screen QGLWidget then
+you may wish to use this QScreen plugin driver. This driver simply returns 0
+(as a EGLNativeWindowType value) when asked by the QtOpenGl module to create a
+native window. Some OpenGL ES implementations (including PowerVR) interpret this
+to mean that a full-screen OpenGL context is desired without any windowing
+support (NullWS).
+
+To tell a Qt/Embedded application to use this driver use the -display command
+line option or the QWS_DISPLAY environment variable. The following driver
+options are supported:
+
+size=WIDTHxHEIGHT   Screen size reported by the driver
+format=FORMAT       Screen format
+
+Run with '-display eglnullws:help' to get a full list of options (including a
+list of supported format strings).
+
+If you choose a screen format that is not supported by the hardware then the
+QtOpenGl module will write out a list of supported EGL configurations. Use
+one of the supported screen formats from this list.
+
+Using this driver with PowerVR hardware
+---------------------------------------
+
+Using this plugin with PowerVR hardware should give a significant speedup
+compared to running with the Qt powervr driver (with a full-screen QGLWidget).
+This is because sacrificing the window system allows less work to be done in
+order to get graphics on the screen. Using this driver also avoids the memory
+fragmentation issues present in the powervr driver and avoids any direct
+dependencies on the deprecated PVR2D API from Imagination Technologies.
+
+To use this driver ensure you have /etc/powervr.ini with contents similar to
+this:
+
+[default]
+WindowSystem=libpvrPVR2D_FLIPWSEGL.so
+
+This driver will also function with libpvrPVR2D_FRONTWSEGL.so, but that draws
+straight into the framebuffer and will therefore cause flickering (it can be
+useful for performance testing though). The flip plugin uses triple buffering,
+so you will need to set the virtual vertical resolution of your framebuffer to
+be three times the physical vertical resolution of your screen. This can be
+done with 'fbset -vyres'. Failure to do this can cause system crashes. You
+should also ensure that the plugin you choose in powervr.ini is in your library
+path (it may just silently default to the flip plugin if not).
