I managed to change both the title and the float handling, but 
unfortunately this involved copying the respective default functions 
from HTML.pm in texinfo, which are licensed under GPLv3+.
The float representation additionally requires the following (copied 
from [1]) added to default.css:
.note {
     margin: 1em;
     border: 1px solid #bbc9d8;
     background-color: #dde1e1;
}

.important {
     margin: 1em;
     border: 1px solid #d26767;
     background-color: #f8e1e1;
}

Not quite, the 'source' is the preferred form of modification, which the 
icon file is probably not.
I don't think the icon was created independently from the main logo, but 
is rather a reduced size version of it. Furthermore the favicon.png says 
it's created by 'Adobe ImageReady', thus the source is probably a PSD file.

It's not really needed, but the HTML documentation still has:
<link rel="icon" href="favicon.png" type="image/png" />

The next sentence there is:
"The rights though should be restricted enough not to allow the art from 
being used for non-FFmpeg representation."

Thus I think it is not possible to release this under a free license, 
which would obviously allow the use for non-FFmpeg representation.
(Correct me, if I'm wrong here, I'm no lawyer.)
I think for this kind of restriction trademarks and not copyright should 
be used.

Anyway, since the license of this icon is not clear, it shouldn't be in 
the release tarball.

Best regards,
Andreas
