Some more cleanup:
- replaced fMsgSender/Receiver with a BPortLink fLink - moved message loop into non-static method _MessageLooper() - renamed Zoom()/Minimize()/Quit()/ScreenModeChanged() to Notify*(), and Quit() to NotfiyQuitRequested() to make more clear what they do (they don't operate on ServerWindow, they just notify its client) - less insane way to init a window: there is no longer the constructor and a separate method Init(); now there is the constructor (which fully sets up the window), InitCheck(), and Run() which runs the window's message loop - moved the quitting stuff into a separate method Quit() and made it callable from other threads. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13247 a95241bf-73f2-0310-859d-f6bbb57e9c96
