    \title Limitations

    \l {Qt Quick} 2 was designed to take full advantage of OpenGL to make the most
    out of available graphics hardware.  By not relying on OpenGL, \RENDERER
    presents certain limitations regarding the available features.

    Since \RENDERER does not use OpenGL, there are some features that cannot be
    supported.  The following are known limitations:

    \section1 Shader Effects
    ShaderEffect components in QtQuick 2 can not be rendered with \RENDERER.

    \section1 Qt Graphical Effects Module
    \l {Qt Graphical Effects} uses ShaderEffect items to render effects. If you use
    graphical effects from this module, then you should not hide the source
    item so that the original item can still be rendered.

    \section1 Particle Effects
    It is not possible to render particle effects with \RENDERER. Whenever
    possible, remove particles completely from the scene. Otherwise they will still
    require some processing, even though they are not visible with \RENDERER.

    \section1 Sprites
    The Sprite item depends on inaccessible OpenGL functions and will
    not be visible.

    \section1 Rendering Text
    The text rendering with \RENDERER is based on software rasterization and does
    not respond as well to transformations such as scaling as when using OpenGL.
    The quality is similar to choosing \l [QML] {Text::renderType}
    {Text.NativeRendering} with \l [QML] {Text} items.

    \section1 Render Control
    QQuickRenderControl depends on OpenGL to function and will not function
    with \RENDERER.  Using QQuickRenderControl can lead to unexpected behavior
    and crashes.
