         *   Set attributes for the WebGL Drawing context. This
         *   is a way of adjusting how the WebGL renderer works
         *   to fine-tune the display and performance. Note
         *   that this will reinitialize the drawing context if
         *   called after the WebGL canvas is made.
         *
         *   If an object is passed as the parameter, all
         *   attributes not declared in the object will be set
         *   to defaults.
         *
         *   The available attributes are:
         *
         *   alpha - indicates if the canvas contains an alpha
         *   buffer default is true
         *
         *   depth - indicates whether the drawing buffer has a
         *   depth buffer of at least 16 bits - default is true
         *
         *   stencil - indicates whether the drawing buffer has
         *   a stencil buffer of at least 8 bits
         *
         *   antialias - indicates whether or not to perform
         *   anti-aliasing default is false (true in Safari)
         *
         *   premultipliedAlpha - indicates that the page
         *   compositor will assume the drawing buffer contains
         *   colors with pre-multiplied alpha default is true
         *
         *   preserveDrawingBuffer - if true the buffers will
         *   not be cleared and and will preserve their values
         *   until cleared or overwritten by author (note that
         *   p5 clears automatically on draw loop) default is
         *   true
         *
         *   perPixelLighting - if true, per-pixel lighting
         *   will be used in the lighting shader otherwise
         *   per-vertex lighting is used. default is true.
         *
         *   version - either 1 or 2, to specify which WebGL
         *   version to ask for. By default, WebGL 2 will be
         *   requested. If WebGL2 is not available, it will
         *   fall back to WebGL 1. You can check what version
         *   is used with by looking at the global webglVersion
         *   property.
