/*
 * 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.
