How about just:
[Constructor(Uint8ClampedArray data, double sw, double sh)]
interface ImageData {
/* Whatever is currently there */
};
and then you create one with:
new ImageData(someData, someWidth, someHeight);
Other than needing to specify whether the array is copied or held on to
by reference, and specifying that this interface should be exposed in
workers, this seems fine to me.
