    elementView.getBBox([opt])

Return a bounding box of the element view.

If `opt.useModelGeometry` option is set to `true`, the resulting bounding box is calculated based on the dimensions of the element model. (This means that SVG sub elements sticking out of the element are excluded.) This behavior is similar to the `element.getBBox` function – but the `elementView` function transforms the bounding box to match `joint.dia.Paper` translation and scaling.
