                I wonder if this is the correct place to post this but I
cannot find any resources online as canvas is so new.


                After grabbing some image data from a canvas with the
getImageData call, I cannot find a way to put the image data onto a canvas
scaled down.


                If I use the canvas scale function and then put the image
data, no scaling occurs. Is there any way to scale with putImageData?


                If not I think it would be a useful addition to the
specification. I can imagine many situations where copying a section of the
canvas and applying scaling before pasting it back to the canvas would be
