clamp rx/ry to valid range (<= 0.5*width/0.5*height)

Browse Source 
SVG spec : ".. If 'rx' is greater than half of the width of the rectangle, then the user agent must process the 'rect' element with the effective value for 'rx' as half of the width of the rectangle. If 'ry' is greater than half of the height of the rectangle, then the user agent must process the 'rect' element with the effective value for 'ry' as half of the height of the rectangle.."
