Animated GIF attached to Timeline does not animate

[GoogleCodeExporter]

XE5 and XE6

Attach an animated gif to the timeline.  Depending on content type you get 
various outcomes but none of them properly show an animated gif in Glass.

You can get an animated GIF to display if you send it as HTML content.  It will 
animate and loop.

As an attachment these are the results based on Content Type:

image/jpeg - shows first frame of animated gif, and overlay message text

image/gif - shows overlay message text only, no image at all, just white text 
on black background

video/mp4 - just a black background (not surprising)

What I expect to happen is to see the animated gif animate and loop when 
attached, I suspect that "image/gif" is the correct content type, even though 
right now image/jpeg works the best.

Here is some sample Java code that reproduces the issue based on the quick 
start project:

        TimelineItem timelineItem = new TimelineItem();
        timelineItem.setText("");
        timelineItem.setNotification(new NotificationConfig().setLevel("DEFAULT"));
        // Attach animated GIF
        String contentType = req.getParameter("contentType");
        URL url = new URL("http://localhost:8888/static/images/animated.gif");
        contentType = "image/jpeg";
        byte[] b = ByteStreams.toByteArray(url.openStream());
        int i = b.length;
        InputStream temp = url.openStream();
        MirrorClient.insertTimelineItem(credential, timelineItem,
                contentType, temp);

Animated GIFs... who knew they'd be such a challenge to support on modern html 
viewports?  ;)

Ha ha, yes.  Low priority seems appropriate, especially since you can get a gif 
to animate if you send it in html.

@markwaersglass - We added some documentation about using Content-ID URIs to 
refer to attachments from within HTML payloads: 
https://developers.google.com/glass/v1/reference/timeline#attachments

This should allow you to render full screen gifs that are unique to (and 
attached to) the timeline item.

This method works, thank you!
