+ * To make your code compile with other GDK backends, guard backend-specific

+ * backends, you should also check for the backend that is in use (e.g. by
+ * using the GDK_IS_MACOS_DISPLAY() macro).

+ * This file implementations integration between the GLib main loop and
+ * the native system of the Core Foundation run loop and Cocoa event
+ * handling. There are basically two different cases that we need to
+ * handle: either the GLib main loop is in control (the application
+ * has called gtk_main(), or is otherwise iterating the main loop), or
+ * CFRunLoop is in control (we are in a modal operation such as window
+ * resizing or drag-and-drop.)
+ *
+ * When the GLib main loop is in control we integrate in native event
+ * handling in two ways: first we add a GSource that handles checking
+ * whether there are native events available, translating native events
+ * to GDK events, and dispatching GDK events. Second we replace the
+ * "poll function" of the GLib main loop with our own version that knows
+ * how to wait for both the file descriptors and timeouts that GLib is
+ * interested in and also for incoming native events.
+ *
+ * When CFRunLoop is in control, we integrate in GLib main loop handling
+ * by adding a "run loop observer" that gives us notification at various
+ * points in the run loop cycle. We map these points onto the corresponding
+ * stages of the GLib main loop (prepare, check, dispatch), and make the
+ * appropriate calls into GLib.
+ *
+ * Both cases share a single problem: the OS X API’s don’t allow us to
+ * wait simultaneously for file descriptors and for events. So when we
+ * need to do a blocking wait that includes file descriptor activity, we
+ * push the actual work of calling select() to a helper thread (the
+ * "select thread") and wait for native events in the main thread.
+ *
+ * The main known limitation of this code is that if a callback is triggered
+ * via the OS X run loop while we are "polling" (in either case described
+ * above), iteration of the GLib main loop is not possible from within
+ * that callback. If the programmer tries to do so explicitly, then they
+ * will get a warning from GLib "main loop already active in another thread".
