JFYI, this does not have anything to do with CSS3.  It is a Microsoft-
proprietary property that is only necessary for that effect in IE/MSHTML
_<_ 9 (IE >= 9 support the “opacity” property, *that* “filter” property has 
been deprecated).

It is not to be confused with the “filter” property of the Filter Effects 
Module specification (WD) that some layout engines implement for CSS and 
that may become part of CSS3 or a higher level.
