Hello Max,

It's one of those annoying cases where there isn't a good solution. 
Filters aren't really css so they can't be controlled as such and no 
positioning can be done with them. All you can do with them is change 
the sizingMethod.

    * scale - scales the image to fit the container a filter is applied to
    * image - resizes the container to the images size
    * crop - crops the image inside the container

Unfortunately the background positioning of the filter is top left. Not 
much you can do about it.

Basically you need to decide if it's really necessary or if you can feed 
a gif to IE instead. Another option is to put an empty div in with 
id="ie-filter" and size and position it to the exact dimensions of the 
filtered background image using the * html hack (IE6 and below only), if 
that makes sense.
