SVG Bounds in PHP

Calculate smallest bounding rectangle for given SVG path strings and points.

Only handles paths composed of straight lines. Bezier and arc commands throw an exception.

Example usage:

 $bounds = SvgBounds::fromPath('M 100 100L300 100 200 300z');
 echo $bounds->getWidth(); //200
 $bounds->extend(350, 100);
 echo $bounds->getWidth(); //250
