Windows processing of image data for icon files can change across os versions
In nsIconChannel we rely on Windows when extracting icon image data from ico files for moz-icons. http://mxr.mozilla.org/mozilla-central/source/image/decoders/icon/win/nsIconChannel.cpp#453 The preprocessing Windows applies to the image data can change across os versions however, which can cause problems for ref tests. (See bug 848963.) I'm not sure if this is a bug that needs to be fixed, but it something we need to be aware of when dealing with ico files.
