+/* MsdOsdWindow is an "on-screen-display" window (OSD).  It is the cute,
+ * semi-transparent, curved popup that appears when you press a hotkey global to
+ * the desktop, such as to change the volume, switch your monitor's parameters,
+ * etc.
+ *
+ * You can create a MsdOsdWindow and use it as a normal GtkWindow.  It will
+ * automatically center itself, figure out if it needs to be composited, etc.
+ * Just pack your widgets in it, sit back, and enjoy the ride.
