ImageData extension type
The ImageData interface represents the underlying pixel data of an
area of a canvas element.
It is created using the ImageData.ImageData constructor or creator methods
on the CanvasRenderingContext2D object associated with a canvas:
CanvasRenderingContext2D.createImageData and
CanvasRenderingContext2D.getImageData. It can also be used to set a part
of the canvas by using CanvasRenderingContext2D.putImageData.
