* This is the internal (private) part of libweston. All symbols found here
* are, and should be only (with a few exceptions) used within the internal
* parts of libweston. Notable exception(s) include a few files in tests/ that
* need access to these functions, screen-share file from compositor/ and those
* remoting/. Those will require some further fixing as to avoid including this
* private header.
*
* Eventually, these symbols should reside naturally into their own scope. New
* features should either provide their own (internal) header or use this one.
