Well I guess the width/height attribute were just added by copy/paste from the 
image tag... So yes, I agree that width/height can be removed for layers (and 
vice/versa for x/y in image).

When it comes to image, the width/height is needed, but optional, if 
width/height isn't defined, then the image has the size of the bounding box.
