CanvasPixelArray
The CanvasPixelArray object provides ordered, indexed access to
the color components of each pixel of the image data. The data
must be represented in left-to-right order, row by row top
to bottom, starting with the top left, with each pixel's
red, green, blue, and alpha components being given in that
order for each pixel. Each component of each device pixel
represented in this array must be in the range 0..255,
representing the 8 bit value for that component. The
components must be assigned consecutive indices starting with
0 for the top left pixel's red component.
