pn.Overlay() layout

[ahuang11]

I was randomly looking at the Discourse icons, and I wonder if we can have a pn.Overlay() to overlay icons over existing widgets?

I imagine having a set of presets, like location to overlay, e.g. top_left, top_right, center, etc, which makes the CSS position sticky or something.

Maybe similar implementation as pn.Swipe.

I don't think I like the idea of pn.Overlay very much but do want to support this use case. Will have to work if there are alternative approaches.
