displayWidth
A Number variable that stores the width of the screen display.
displayWidth is useful for running full-screen programs. Its value depends on the current pixelDensity().
Note: The actual screen width can be computed as displayWidth * pixelDensity().
Examples

function setup()
-- Set the canvas' width and height
-- using the display's dimensions.
size(displayWidth, displayHeight)
background(200)
describe('A gray canvas that is the same size as the display.')
end
