        I think it's time for a drawing thread inside app_server.
        ATM invalidating and drawing is done from almost every thread in 
app_server. IMHO this is not that 
good as we do need a lot of locking, and code flow is hard to follow.
        I propose we have methods like ::Invalidate, ::Redraw, which if 
executed from another thread than 
this drawing_thread, automatically send port messages for the requested action.

        In this thread I think it is better we also execute window manager's 
code. This thread would wait 
for input data (mouse events, keyboard events, invalidate_or_redraw_messages) 
move/resize/hide/show windows by calling ::Invalidate and :: Redraw() methods.

        Comments, suggestions?
