/**
   * Creates a new PGraphics object and sets it to the specified size.
   *
   * Note that you cannot change the renderer once outside of setup().
   * In most cases, you can call size() to give it a new size,
   * but you need to always ask for the same renderer, otherwise
   * you're gonna run into trouble.
   *
   * The size() method should *only* be called from inside the setup() or
   * draw() methods, so that it is properly run on the main animation thread.
   * To change the size of a PApplet externally, use setSize(), which will
   * update the component size, and queue a resize of the renderer as well.
