Carlos Garnacho 3f8e4d515e frames: Add new X11 frames client ... This small X11 client takes care of creating frames for client windows, Mutter will use this client to delegate window frame rendering and event handling. The MetaWindowTracker object will keep track of windows created from other clients, and will await for _MUTTER_NEEDS_FRAME property updates on those (coming from Mutter), indicating the need for a frame window. This process is resilient to restarts of the frames client, existing windows will be queried during start, and the existence of relevant properties checked. Mutter will be able to just hide/show SSD-decorated windows while the frames client restarts. The frames are created through GTK4 widgets, the MetaWindowContent widget acts as a replacement prop for the actual client window, and the MetaFrameHeader wraps GtkHeaderBar so that windows can be overshrunk, but otherwise a MetaFrame is a 100% true GTK4 GtkWindow. After a frame window is created for a client window, the _MUTTER_FRAME_FOR property will be set on the frame window, indicating to mutter the correspondence between both Windows. Additionally, the pixel sizes of the visible left/right/top/bottom borders of the frame will be set through the _MUTTER_FRAME_EXTENTS property, set on the frame window. In order to make the frame window behave as the frame for the client window, a number of properties will be tracked from the client window to update the relevant frame behavior (window title, resizability, availability of actions...), and also some forwarding of events happening in the frame will be forwarded to the client window (mainly, WM_DELETE_WINDOW when the close button is clicked). Other than that, the frames are pretty much CSD GTK4 windows, so window drags and resizes, and window context menus are forwarded for the WM to handle.
