     To create your own custom effect, create a subclass of QGraphicsEffect (or
     any other existing effects) and reimplement the virtual function draw().
     This function is called whenever the effect needs to redraw. The draw()
-    function accepts two arguments: the painter and a pointer to the source
-    (QGraphicsEffectSource). The source provides extra context information,
-    such as a pointer to the item that is rendering the effect, any cached
-    pixmap data, or the device rectangle bounds. For more information, refer to
-    the documenation for draw(). To obtain a pointer to the current source,
-    simply call source().
+    function takes the painter with which to draw as an argument. For more
+    information, refer to the documenation for draw(). In the draw() function
+    you can call sourcePixmap() to get a pixmap of the graphics effect source
+    which you can then process.
 
     If your effect changes, use update() to request for a redraw. If your
     custom effect changes the bounding rectangle of the source, e.g., a radial
     glow effect may need to apply an extra margin, you can reimplement the
-    virtual boundingRectFor() function, and call updateBoundingRect() to notify
-    the framework whenever this rectangle changes. The virtual

-    Calculate the "expanding" keyframe
-
-    This new keyframe sits between the already existing sizeAtPreferred and
-    sizeAtMaximum keyframes. Its goal is to modify the interpolation between
-    the latter as to respect the "expanding" size policy of some anchors.
-
-    Previously all items would be subject to a linear interpolation between
-    sizeAtPreferred and sizeAtMaximum values. This will change now, the
-    expanding anchors will change their size before the others. To calculate
-    this keyframe we use the following logic:
-
-    1) Ask each anchor for their desired expanding size (ad->expSize), this
-    value depends on the anchor expanding property in the following way:
-
-    - Expanding normal anchors want to grow towards their maximum size
-    - Non-expanding normal anchors want to remain at their preferred size.
-    - Sequential anchors wants to grow towards a size that is calculated by:
-        summarizing it's child anchors, where it will use preferred size for non-expanding anchors
-        and maximum size for expanding anchors.
-    - Parallel anchors want to grow towards the smallest maximum size of all the expanding anchors.
-
-    2) Clamp their desired values to the value they assume in the neighbour
-    keyframes (sizeAtPreferred and sizeAtExpanding)
-
-    3) Run simplex with a setup that ensures the following:
-
-      a. Anchors will change their value from their sizeAtPreferred towards
-         their sizeAtMaximum as much as required to ensure that ALL anchors
-         reach their respective "desired" expanding sizes.
-
-      b. No anchors will change their value beyond what is NEEDED to satisfy
-         the requirement above.
-
-    The final result is that, at the "expanding" keyframe expanding anchors
-    will grow and take with them all anchors that are parallel to them.
-    However, non-expanding anchors will remain at their preferred size unless
-    they are forced to grow by a parallel expanding anchor.
-
-    Note: For anchors where the sizeAtPreferred is bigger than sizeAtMaximum,
-          the visual effect when the layout grows from its preferred size is
-          the following: Expanding anchors will keep their size while non
-          expanding ones will shrink. Only after non-expanding anchors have
-          shrinked all the way, the expanding anchors will start to shrink too.

+ same code needed at both places. This solution makes it more difficult
+ to e.g fix a bug in qcocoawindow_mac.mm, but forget to do the same in
+ qcocoapanel_mac.mm.
+ The reason we need to do copy and paste in the first place, rather than
+ resolve to method overriding, is that QCocoaPanel needs to inherit from
+ NSPanel, while QCocoaWindow needs to inherit NSWindow rather than NSPanel).

     The function pos() gives the current cursor position, while oldPos() gives
     the old mouse position.
+
+    There are a few similarities between the events QEvent::HoverEnter
+    and QEvent::HoverLeave, and the events QEvent::Enter and QEvent::Leave.
+    However, they are slightly different because we do an update() in the event
+    handler of HoverEnter and HoverLeave.
+
+    QEvent::HoverMove is also slightly different from QEvent::MouseMove. Let us
+    consider a top-level window A containing a child B which in turn contains a
+    child C (all with mouse tracking enabled):
+
+    \image hoverevents.png
+
+    Now, if you move the cursor from the top to the bottom in the middle of A,
+    you will get the following QEvent::MouseMove events:
+
+    \list 1
+        \o A::MouseMove
+        \o B::MouseMove
+        \o C::MouseMove
+    \endlist
+
+    You will get the same events for QEvent::HoverMove, except that the event
+    always propagates to the top-level regardless whether the event is accepted
+    or not. It will only stop propagating with the Qt::WA_NoMousePropagation
+    attribute.
+
+    In this case the events will occur in the following way:
+
+    \list 1
+        \o A::HoverMove
+        \o A::HoverMove, B::HoverMove
+        \o A::HoverMove, B::HoverMove, C::HoverMove

+    \section1 Performance
+
+    QPainter is a rich framework that allows developers to do a great
+    variety of graphical operations, such as gradients, composition
+    modes and vector graphics. And QPainter can do this across a
+    variety of different hardware and software stacks. Naturally the
+    underlying combination of hardware and software has some
+    implications for performance, and ensuring that every single
+    operation is fast in combination with all the various combinations
+    of composition modes, brushes, clipping, transformation, etc, is
+    close to an impossible task because of the number of
+    permutations. As a compromise we have selected a subset of the
+    QPainter API and backends, were performance is guaranteed to be as
+    good as we can sensibly get it for the given combination of
+    hardware and software.
+
+    The backends we focus on as high-performance engines are:
+
+    \list
+
+    \o Raster - This backend implements all rendering in pure software
+    and is always used to render into QImages. For optimal performance
+    only use the format types QImage::Format_ARGB32_Premultiplied,
+    QImage::Format_RGB32 or QImage::Format_RGB16. Any other format,
+    including QImage::Format_ARGB32, has significantly worse
+    performance. This engine is also used by default on Windows and on
+    QWS. It can be used as default graphics system on any
+    OS/hardware/software combination by passing \c {-graphicssystem
+    raster} on the command line
+
+    \o OpenGL 2.0 (ES) - This backend is the primary backend for
+    hardware accelerated graphics. It can be run on desktop machines
+    and embedded devices supporting the OpenGL 2.0 or OpenGL/ES 2.0
+    specification. This includes most graphics chips produced in the
+    last couple of years. The engine can be enabled by using QPainter
+    onto a QGLWidget or by passing \c {-graphicssystem opengl} on the
+    command line when the underlying system supports it.
+
+    \o OpenVG - This backend implements the Khronos standard for 2D
+    and Vector Graphics. It is primarily for embedded devices with
+    hardware support for OpenVG.  The engine can be enabled by
+    passing \c {-graphicssystem openvg} on the command line when
+    the underlying system supports it.
+
+    \endlist
+
+    These operations are:
+
+    \list
+
+    \o Simple transformations, meaning translation and scaling, pluss
+    0, 90, 180, 270 degree rotations.
+
+    \o \c drawPixmap() in combination with simple transformations and
+    opacity with non-smooth transformation mode
+    (\c QPainter::SmoothPixmapTransform not enabled as a render hint).
+
+    \o Text drawing with regular font sizes with simple
+    transformations with solid colors using no or 8-bit antialiasing.
+
+    \o Rectangle fills with solid color, two-color linear gradients
+    and simple transforms.
+
+    \o Rectangular clipping with simple transformations and intersect
+    clip.
+
+    \o Composition Modes \c QPainter::CompositionMode_Source and
+    QPainter::CompositionMode_SourceOver
+
+    \o Rounded rectangle filling using solid color and two-color
+    linear gradients fills.
+
+    \o 3x3 patched pixmaps, via qDrawBorderPixmap.
+
+    \endlist
+
+    This list gives an indication of which features to safely use in
+    an application where performance is critical. For certain setups,
+    other operations may be fast too, but before making extensive use
+    of them, it is recommended to benchmark and verify them on the
+    system where the software will run in the end. There are also
+    cases where expensive operations are ok to use, for instance when
+    the result is cached in a QPixmap.
