The SVG_SET_SHAPE_RENDERING command can be used to set which tradeoffs should be made regarding the rendering of graphic elements for the object designated by svgObject. If svgObject is not an SVG object, an error is generated.
The rendering parameter must contain one of the following values: "auto", "optimizeSpeed", "crispEdges", "geometricPrecision" or "inherit". Otherwise, an error is generated.
