/* 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.
