\class ServerWindow
\brief Shadow BWindow class
A ServerWindow handles all the intraserver tasks required of it by its BWindow. There are
too many tasks to list as being done by them, but they include handling View transactions,
coordinating and linking a window's Window half with its messaging half, dispatching
mouse and key events from the server to its window, and other such things.
/*! \class ServerWindow
The ServerWindow class handles all BWindow messaging; it forwards all
BWindow requests to the corresponding app_server classes, that is Desktop,
Window, and View.
Furthermore, it also sends app_server requests/notices to its BWindow. There
is one ServerWindow per BWindow.
