x11: Integrate frames client into Mutter Replace the in-process implementation of frames with the external frames client. When a client window is created and managed by Mutter, Mutter will determine whether it is a window that requires decorations and hint the creation of a frame for it by setting the _MUTTER_NEEDS_FRAME property on the client window. After the frames client created a window that has the _MUTTER_FRAME_FOR property, Mutter will proceed to reparent the client window on the frame window, and show them as a single unit. Rendering and event handling on the frame window will be performed by the external client, Mutter is still responsible for everything else, namely resizing client and frame window in synchronization, and managing updates on the MetaWindowActor. In order to let the frame be managed by the external client, Mutter needs to change the way some properties are forwarded to the client and/or frame windows. Some properties are necessary to keep propagating to the client window only, some others need to happen on the frame window now, and some others needs to be propagated on both so they are synchronized about the behavior. Also, some events that were previously totally unexpected in frame windows are now susceptible to happen, so must be allowed now. MetaFrame in src/core/frame.c now acts as the wrapper of foreign windows created by the frames client, from the Mutter side. Location, size, and lifetime are still largely in control of Mutter, some details like visible/invisible borders are obtained from the client instead (through the _MUTTER_FRAME_EXTENTS and _GTK_FRAME_EXTENTS properties, respectively).
