/** The Clipboard object represents a clipboard of data shared between different processes or between
 * different widgets in the same process. Each clipboard is identified by a name encoded as a GdkAtom. *
 * (Conversion to and from strings can be done with gdk_atom_intern() and gdk_atom_name().) The default
 * clipboard corresponds to the "CLIPBOARD" atom; another commonly used clipboard is the "PRIMARY" clipboard,
 * which, in X, traditionally contains the currently selected text.
 *
 * To support having a number of different formats on the clipboard at the same time, the clipboard mechanism
 * allows providing callbacks instead of the actual data. When you set the contents of the clipboard, you can
 * either supply the data directly (via functions like set_text()), or you can supply a callback
 * to be called at a later time when the data is needed (via set().) Providing a callback also avoids having to
 * make copies of the data when it is not needed.
 *
 * Requesting the data from the clipboard is essentially asynchronous. If the contents of the clipboard are
 * provided within the same process, then a direct function call will be made to retrieve the data, but if they
 * are provided by another process, then the data needs to be retrieved from the other process, which may take
 * some time. To avoid blocking the user interface, the call to request the selection, request_contents() takes
 * a callback that will be called when the contents are received (or when the request fails.) If you don't want
 * to deal with providing a separate callback, you can also use wait_for_contents(). This runs the
 * GLib main loop recursively waiting for the contents. This can simplify the code flow, but you still have to
 * be aware that other callbacks in your program can be called while this recursive mainloop is running.
 *
 * Along with the functions to get the clipboard contents as an arbitrary data chunk, there are also functions
 * to retrieve it as text, request_text() and wait_for_text(). These functions take
 * care of determining which formats are advertised by the clipboard provider, asking for the clipboard in the
 * best available format and converting the results into the UTF-8 encoding.
