Warning
gtk_socket_steal is deprecated and should not be used in newly-written code.
Reparents a pre-existing toplevel window into a GtkSocket. This is
meant to embed clients that do not know about embedding into a
GtkSocket, however doing so is inherently unreliable, and using
this function is not recommended.
The GtkSocket must have already be added into a toplevel window
before you can make this call.
