 By default, `p5.Framebuffer`s are not drawn to the screen. The main canvas is the only thing shown at the end of `draw()`. To make the contents of a `p5.Framebuffer` visible, it has to be stamped upon the main canvas. This is typically done with a call to `image(yourFramebuffer, x, y, width, height)`. Similar to the main canvas, a `p5.Framebuffer` only gets cleared when you ask it to be cleared, so you can stamp it on the main canvas as many times as you want, like in the example below.
