This class creates a window and a worker thread.
The worker thread pulls messages from the window's input queue and dispatches them as appropriate.
The window and its thread are created by the CBaseWindow::PrepareWindow member function and destroyed by the CBaseWindow::DoneWithWindow member function.
The window should also be initialized by the CBaseWindow::InitialiseWindow member function and uninitialized by the CBaseWindow::UninitialiseWindow member function.
After preparing and initializing a window, size it by using the CBaseWindow::ActivateWindow member function; hide the window using the CBaseWindow::InactivateWindow member function.
