Comment:
createImageBitmap() references the ImageData object's pixel density, which is
currently undefined. We should probably have getImageData() and
createImageData() create ImageData objects with 1dpppx density, and
getImageDataHD() and createImageDataHD() create ImageData objects with the
canvas' native density, and that density should be propagated through
postMessage(), etc.

Checked in as WHATWG revision r7849.
Check-in comment: ImageData objects now expose an explicit pixel density, enabling them to be converted to BitmapImage objects correctly.
