*
* @property string $encoding
* Encoding of the SVG XML document
* @property float $assumedNumericCharacterWidth
* Assumed percentual average width of chars in numeric strings with
* the used font.
* @property float $assumedTextCharacterWidth
* Assumed percentual average width of chars in non numeric strings
* with the used font.
* @property string $strokeLineCap
* This specifies the shape to be used at the end of open subpaths
* when they are stroked.
* @property string $strokeLineJoin
* This specifies the shape to be used at the edges of paths.
* @property string $shapeRendering
* "The creator of SVG content might want to provide a hint to the
* implementation about what tradeoffs to make as it renders vector
* graphics elements such as 'path' elements and basic shapes such as
* circles and rectangles."
* @property string $colorRendering
* "The creator of SVG content might want to provide a hint to the
* implementation about how to make speed vs. quality tradeoffs as it
* performs color interpolation and compositing. The
* 'color-rendering' property provides a hint to the SVG user agent
* about how to optimize its color interpolation and compositing
* operations."
* @property string $textRendering
* "The creator of SVG content might want to provide a hint to the
* implementation about what tradeoffs to make as it renders text."
* @property mixed $templateDocument
* Use existing SVG document as template to insert graph into. If
* insertIntoGroup is not set, a new group will be inserted in the
* svg root node.
* @property mixed $insertIntoGroup
* ID of a SVG group node to insert the graph. Only works with a
* custom template document.
* @property ezcGraphCoordinate $graphOffset
* Offset of the graph in the svg.
* @property string $idPrefix
* Prefix used for the ids in SVG documents.
* @property string $linkCursor
* CSS value for cursor property used for linked SVG elements
