     Another example is QEasingCurve::InOutElastic, which provides an

+    transform the "normalized progress" (currentTime / totalDuration)
+    of the animation into the effective progress actually
+    used by the animation. It is this effective progress that will be

     control how the current value changes as the animation progresses.

     Another workaround is to convert the paths to polygons first and then draw the

+    \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.
