/*
* When the plug and socket are in separate processes they use a
* simple protocol, more or less based on XEMBED. The protocol uses
* registered window messages. The name passed to
* RegisterWindowMessage() is gtk-win32-embed:%d, with %d being the
* numeric value of an GtkWin32EmbedMessageType enum. Each message
* carries the message type enum value and two integers, the "wparam"
* and "lparam", like all window messages.
*
* So far all the window messages are posted to the other
* process. Maybe some later enhancement will add also messages that
* are sent, i.e. where the sending process waits for the receiving
* process's window procedure to handle the message.
