Creating Bitmap Images

   * The basic way to create bitmap images is to use the saveFrame() function.
   * If you want to create a really large scene and write that, first make sure that you've allocated a lot of memory.
   * If you want to create images that are larger than the screen, you should create your own PGraphics object, draw to that, and use save(). For now, it's best to use P3D in this scenario. P2D is currently disabled, and the JAVA2D default will give mixed results. So for instance:
Code:

	PGraphics big;

	void setup() {
	  big = createGraphics(3000, 3000, P3D);

	  big.beginDraw();
	  big.background(128);
	  big.line(20, 1800, 1800, 900);
	  // etc..
	  big.endDraw();

	  // make sure the file is written to the sketch folder
	  String path = savePath("big.tif");
	  big.save(path);
	}
