-    \qmlclass Blur QGraphicsBlurEffect
-    \since 4.7
-    \brief The Blur object provides a blur effect.
-
-    A blur effect blurs the source item. This effect is useful for reducing details;
-    for example, when the a source loses focus and attention should be drawn to other
-    elements. Use blurRadius to control the level of detail and blurHint to control
-    the quality of the blur.
-
-    By default, the blur radius is 5 pixels.
-
-    \img graphicseffect-blur.png

-
-/*!
-    \qmlproperty real Blur::blurRadius
-
-    This controls how blurry an item will appear.
-
-    A smaller radius produces a sharper appearance, and a larger radius produces
-    a more blurred appearance.
-
-    The default radius is 5 pixels.
-*/
-/*!
-    \qmlproperty enumeration Blur::blurHint
-
-    Use Qt.PerformanceHint to specify a faster blur or Qt.QualityHint hint
-    to specify a higher quality blur.
-   
-    If the blur radius is animated, it is recommended you use Qt.PerformanceHint.
-
-    The default hint is Qt.PerformanceHint.

-/*!
-    \qmlclass Colorize QGraphicsColorizeEffect
-    \since 4.7
-    \brief The Colorize object provides a colorize effect.
-
-    A colorize effect renders the source item with a tint of its color.
-
-    By default, the color is light blue.

-    \qmlproperty real Colorize::strength

-/*!
-    \qmlclass DropShadow QGraphicsDropShadowEffect
-    \since 4.7
-    \brief The DropShadow object provides a drop shadow effect.
-
-    A drop shadow effect renders the source item with a drop shadow. The color of
-    the drop shadow can be modified using the color property. The drop
-    shadow offset can be modified using the xOffset and yOffset properties and the blur
-    radius of the drop shadow can be changed with the blurRadius property.
-
-    By default, the drop shadow is a semi-transparent dark gray shadow,
-    blurred with a radius of 1 at an offset of 8 pixels towards the lower right.

-*/
-
-/*!
-    \qmlproperty real DropShadow::blurRadius
-    The blur radius in pixels of the drop shadow.
-
-    Using a smaller radius results in a sharper shadow, whereas using a bigger
-    radius results in a more blurred shadow.
-
-    By default, the blur radius is 1 pixel.

-    \qmlproperty color DropShadow::color

-/*!
-    \qmlclass Opacity QGraphicsOpacityEffect
-    \since 4.7
-    \brief The Opacity object provides an opacity effect.
-
-    An opacity effect renders the source with an opacity. This effect is useful
-    for making the source semi-transparent, similar to a fade-in/fade-out
-    sequence. The opacity can be modified using the opacity property.
-
-    By default, the opacity is 0.7.
-
-    \img graphicseffect-opacity.png

-
-/*!
-    \qmlproperty real Opacity::opacity
-    This property specifies how opaque an item should appear.
-
-    The value should be in the range of 0.0 to 1.0, where 0.0 is
-    fully transparent and 1.0 is fully opaque.
-
-    By default, the opacity is 0.7.
