The window will be stored in a pixmap of the size of the window as if it
were unshaped; areas beyond the shape will be undefined. Automatic
compositing will copy only those areas within the shape. Manual
compositing should respect the shape. xcompmgr demonstrates how to do
this by constructing a region from the window clip list.
