new Camera(x, y, zoom)
Look at the Camera reference pages before reading these docs. A `camera` object is created automatically when p5play loads. Currently, there can only be one camera per p5.js instance. A camera facilitates scrolling and zooming for scenes extending beyond the canvas. A camera has a position, a zoom factor, and the mouse coordinates relative to the view. The camera is automatically created on the first draw cycle. In p5.js terms the camera wraps the whole drawing cycle in a transformation matrix but it can be disable anytime during the draw cycle for example to draw interface elements in an absolute position.
