/**
 * A High Order Component (HOC) function that provides
 * the contextual `width` and `height` props to a GL Component.
 * It also merge optional width,height props to override the contextual size
 * @function connectSize
 * @param GLComponent - a React Component that receives width and height props
 * @returns {ReactClass<*>} a Component that merge width and height props
 * with context and renders `GLComponent`.
 * @example
 *  const Foo = ({ width, height }) => <Node uniforms={{ width, height }} />;
 *  const FooConnected = connectSize(Foo);
 *  <FooConnected /> // you don't have to provide width, height.
 *  <FooConnected width={64} height={64} /> // If you do, you override width,height in the context as well, so <Node> is implicitly receiving the new width/height.
