[css3-background] background-size and background-position

background-position should be defined in such a way that it takes the  
resulting size of the image into account and not be based on the original  
size of the image. A line saying that references to the dimensions of the  
image refer to the size after background-size has been applied would  
suffice I think. For -o-background-size we currently implement the  
non-intuitive version and are planning to change this.
