	 * Sets an offset in a larger frustum. This is useful for multi-window or

	 *```
	 *   +---+---+---+
	 *   | A | B | C |
	 *   +---+---+---+
	 *   | D | E | F |
	 *   +---+---+---+
	 *```
	 * then for each monitor you would call it like this:
	 *```js
	 * const w = 1920;
	 * const h = 1080;
	 * const fullWidth = w * 3;
	 * const fullHeight = h * 2;
	 *
	 * // --A--
	 * camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 0, w, h );
	 * // --B--
	 * camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 0, w, h );
	 * // --C--
	 * camera.setViewOffset( fullWidth, fullHeight, w * 2, h * 0, w, h );
	 * // --D--
	 * camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 1, w, h );
	 * // --E--
	 * camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 1, w, h );
	 * // --F--
