Add new window type TYPE_DRAWN_APPLICATION

This type behaves like a normal TYPE_APPLICATION, except that WM
will always wait for it to be drawn before starting a transition.

WM always waits for TYPE_BASE_APPLICATION (main window), but for
TYPE_APPLICATION, it only waits if the window relayouts to visible
and gets a surface before the main window is drawn. If main window
itself is ready very fast, transition could start without the other
window.
