But you can't! The XID of a window is always different per session. so
unless you're doing something really weird (which would be horror on
itself), this won't work.

Properties don't have type-checking, and properties are merely meant as
user-settable things. ID is purely programmatically interesting, the end
user cannot use it, so it shouldn't be a property.

No. Overlay is "putting video on the desktop. It's just a name. You'll
always create elements (e.g. xvideosink), and you know want an element
that implements the xoverlay interface. In the future, we might make a
function to get the "best element" that implements a given interface.
However, we don't have that yet.
