Bug

What is the current behavior?

Currently the recharts tooltip has some incorrect viewBox default props set https://github.com/recharts/recharts/blob/master/src/component/Tooltip.tsx#L103

  viewBox: { x1: 0, x2: 0, y1: 0, y2: 0 },

current viewBox properties are x, y, height, width

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: http://jsfiddle.net/ndLhnegs/).

What is the expected behavior?

Use the correct props + test that the correct props don't break anything
