  smooth();//Draws all geometry with smooth (anti-aliased) edges. smooth() will also improve image quality of resized images. Note that smooth() is active by default; noSmooth() can be used to disable smoothing of geometry, images, and fonts.
  noLoop();//Stops Processing from continuously executing the code within draw(). If loop() is called, the code indraw() begins to run continuously again. If using noLoop() in setup(), it should be the last line inside the block.
