Initial import from the monolithic Qt.
This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12

+ \class QGraphicsSvgItem
+ \ingroup graphicsview-api
+ \brief The QGraphicsSvgItem class is a QGraphicsItem that can be used to render
+ the contents of SVG files.
+
+ \since 4.2
+
+ QGraphicsSvgItem provides a way of rendering SVG files onto QGraphicsView.
+ QGraphicsSvgItem can be created by passing the SVG file to be rendered to
+ its constructor or by explicit setting a shared QSvgRenderer on it.
+
+ Note that setting QSvgRenderer on a QGraphicsSvgItem doesn't make the item take
+ ownership of the renderer, therefore if using setSharedRenderer() method one has
+ to make sure that the lifetime of the QSvgRenderer object will be at least as long
+ as that of the QGraphicsSvgItem.
+
+ QGraphicsSvgItem provides a way of rendering only parts of the SVG files via
+ the setElementId. If setElementId() method is called, only the SVG element
+ (and its children) with the passed id will be renderer. This provides a convenient
+ way of selectively rendering large SVG files that contain a number of discrete
+ elements. For example the following code renders only jokers from a SVG file
+ containing a whole card deck:
+
+ \snippet doc/src/snippets/code/src_svg_qgraphicssvgitem.cpp 0
+
+ Size of the item can be set via the \l{QRectF::setSize()}
+ {setSize()} method of the \l{QGraphicsSvgItem::boundingRect()}
+ {bounding rectangle} or via direct manipulation of the items
+ transformation matrix.
+
+ By default the SVG rendering is cached using QGraphicsItem::DeviceCoordinateCache
+ mode to speedup the display of items. Caching can be disabled by passing
+ QGraphicsItem::NoCache to the QGraphicsItem::setCacheMode() method.

+ \class QSvgGenerator
+ \ingroup painting
+ \since 4.3
+ \brief The QSvgGenerator class provides a paint device that is used to create SVG drawings.
+ \reentrant
+
+ This paint device represents a Scalable Vector Graphics (SVG) drawing. Like QPrinter, it is
+ designed as a write-only device that generates output in a specific format.
+
+ To write an SVG file, you first need to configure the output by setting the \l fileName
+ or \l outputDevice properties. It is usually necessary to specify the size of the drawing
+ by setting the \l size property, and in some cases where the drawing will be included in
+ another, the \l viewBox property also needs to be set.
+
+ \snippet examples/painting/svggenerator/window.cpp configure SVG generator
+
+ Other meta-data can be specified by setting the \a title, \a description and \a resolution
+ properties.
+
+ As with other QPaintDevice subclasses, a QPainter object is used to paint onto an instance
+ of this class:
+
+ \snippet examples/painting/svggenerator/window.cpp begin painting
+ \dots
+ \snippet examples/painting/svggenerator/window.cpp end painting
+
+ Painting is performed in the same way as for any other paint device. However,
+ it is necessary to use the QPainter::begin() and \l{QPainter::}{end()} to
+ explicitly begin and end painting on the device.
+
+ The \l{SVG Generator Example} shows how the same painting commands can be used
+ for painting a widget and writing an SVG file.

+ \class QSvgRenderer
+ \ingroup painting
+
+ \brief The QSvgRenderer class is used to draw the contents of SVG files onto paint devices.
+ \since 4.1
+ \reentrant
+
+ Using QSvgRenderer, Scalable Vector Graphics (SVG) can be rendered onto any QPaintDevice
+ subclass, including QWidget, QImage, and QGLWidget.
+
+ QSvgRenderer provides an API that supports basic features of SVG rendering, such as loading
+ and rendering of static drawings, and more interactive features like animation. Since the
+ rendering is performed using QPainter, SVG drawings can be rendered on any subclass of
+ QPaintDevice.
+
+ SVG drawings are either loaded when an QSvgRenderer is constructed, or loaded later
+ using the load() functions. Data is either supplied directly as serialized XML, or
+ indirectly using a file name. If a valid file has been loaded, either when the renderer
+ is constructed or at some later time, isValid() returns true; otherwise it returns false.
+ QSvgRenderer provides the render() slot to render the current document, or the current
+ frame of an animated document, using a given painter.
+
+ The defaultSize() function provides information about the amount of space that is required
+ to render the currently loaded SVG file. This is useful for paint devices, such as QWidget,
+ that often need to supply a size hint to their parent layout.
+ The default size of a drawing may differ from its visible area, found using the \l viewBox
+ property.
+
+ Animated SVG drawings are supported, and can be controlled with a simple collection of
+ functions and properties:
+
+ \list
+ \o The animated() function indicates whether a drawing contains animation information.
+ \omit
+ \o The animationDuration() function provides the duration in milliseconds of the
+ animation, without taking any looping into account.
+ \o The \l currentFrame property contains the current frame of the animation.
+ \endomit
+ \o The \l framesPerSecond property contains the rate at which the animation plays.
+ \endlist
+
+ Finally, the QSvgRenderer class provides the repaintNeeded() signal which is emitted
+ whenever the rendering of the document needs to be updated.

+/*!
+ \class QSvgWidget
+ \ingroup painting
+
+ \brief The QSvgWidget class provides a widget that is used to display the contents of
+ Scalable Vector Graphics (SVG) files.
+ \since 4.1
+
+ This class enables developers to display SVG drawings alongside standard widgets, and
+ is used in much the same way as QLabel is used for displaying text and bitmap images.
+
+ Since QSvgWidget is a subclass of QWidget, SVG drawings are rendered using the properties
+ of the display. More control can be exercised over the rendering process with the
+ QSvgRenderer class, as this can be used to paint onto other paint devices, such as QImage
+ and QGLWidget. The renderer used by the widget can be obtained with the renderer()
+ function.
+
+ Each QSvgWidget can be constructed with the file name of a SVG file, or they can be
+ constructed without a specific file to render and one can be supplied later. The load()
+ functions provide two different ways to load an SVG file: they accept either the file name
+ of an SVG file or a QByteArray containing the serialized XML representation of an SVG file.
+
+ By default, the widget provides a size hint to reflect the size of the drawing that it
+ displays. If no data has been loaded, the widget provides the default QWidget size hint.
+ Subclass this class and reimplement sizeHint() if you need to customize this behavior.
