A react component that wraps and autosizes a canvas element
import React, {PropTypes} from 'react';
import { debounce } from 'lodash';
// A simple helper component, wrapping retina logic for canvas and
// auto-resizing the canvas to fill its parent container.
// To determine size/layout, we just use CSS on the div containing
// the Canvas component (we're using this with flexbox, for example).
// Expects a "paint" function that takes a "context" to draw on
// Whenever this component updates it will call this paint function
// to draw on the canvas. For convenience, pixel dimensions are stored
