Sets the bounding rectangle for element made up of the X, Y, Width, and Height properties (at the RSSVG.TSVGGraphicElement level) with no transformations applied. The values are the virtual "pixel" values using the nearest viewbox. For example, if the nearest viewbox (say the TSVGDocument specify a viewbox of 0, 0, 100, 100, a value of 50, 50 is exactly in the middle of the viewbox, regardless of the amount of pixels the TSVGDocument is being drawn to.
TSVGElement.SetBoundsRect does nothing. This method is overridden by descendant classes
