The filter property is an extension that IE supports. Its  
(potentially) useful for loading DirectX/ActiveX components that  
provide visual effects.

Its frequently used to load png images that utilize the alpha channel  
since IE6 doesn't support that by default.

I've not seen it used for much besides gradients and loading pngs in  
the wild, though someone like Ian could provide more insight to how  
prevalent its usage is.

ex:
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader  
(src='image.png', sizingMethod='scale');
