Summary: IE CSS filters are broken
           Product: Wine
           Version: 0.9.21.
          Platform: All
               URL: http://brodierao.com/etc/wine/filters.html
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-shdocvw
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

With Wine 0.9.21 (and older versions), Internet Explorer's proprietary CSS
"filter" property does not work. This is commonly used to provide alpha
transparency for PNGs in IE6 and IE5.5 (IE4 supports it with different filter
names). The URL in this bug report shows a very basic example of a CSS filter,
but for an example of alpha transparency in PNGs, see
http://webfx.eae.net/dhtml/pngbehavior/demo.html . More information can be found
at MSDN: http://msdn.microsoft.com/workshop/author/filter/filters.asp .

I didn't see any interesting message with WINEDEBUG set to "fixme+all". I get
the same gist of messages for any page, regardless of what CSS filters are
present, but I can attach a log if necessary.

I also would like to say this is a fairly important feature for web designers
and programmers. I implement web designs, which frequently employ advanced
effects such as translucency, and not being able to test that without Windows is
a bit of an annoyance.

Also, I'm not entirely sure if wine-shdocvw is the right component for this bug
report, so forgive me if that's incorrect.
