Some suggested language in section 3.12.11.1.11(!):
Instead of:

I would suggest:
The first argument to the method must be an ImageData object returned
by createImageData(), getImageData(), or an object constructed with
the necessary properties by the user. If the object was constructed
by the user, its width and height dimensions are specified in device
pixels (which may not map directly to CSS pixels). If null or any
other object is given that does not present the ImageData interface,
then the putImageData() method must raise a TYPE_MISMATCH_ERR exception.
