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

   *
   *   +---+---+---+
   *   | A | B | C |
   *   +---+---+---+
   *   | D | E | F |
   *   +---+---+---+
   *

   *
   *   const w = 1920;
   *   const h = 1080;
   *   const fullWidth = w * 3;
   *   const fullHeight = h * 2;
   *
