Display captions with author and title

[jvolker]

Following up from #44 and https://groups.google.com/forum/#!topic/openframeio/Zz6hGQ_6GO8

Let's use this thread to discuss if there are any options to display captions with author and artwork title.

This should be easy in the website extension as we could wrap the content in an iframe and overlay it with a container for captions.

Such layering is not easy to do in other extensions. Though, I was wondering, if there was anything like transparent windows and layering of windows in x server? That would allow rendering captions in a separate window that could be overlayed over the native application used by the extension? Does anyone know more about this?
