Typically, to stream the content of a window, we need a way to copy the content of its window-actor into a buffer, transform relative input coordinates to relative position within the window-actor and a mean to get the window bounds within the buffer. For this purpose, add a new GType interface `MetaScreenCastWindow` with the methods needed for screen-cast window mode: * meta_screen_cast_window_get_buffer_bounds() * meta_screen_cast_window_get_frame_bounds() * meta_screen_cast_window_transform_relative_position() * meta_screen_cast_window_capture_into() This interface is meant to be implemented by `MetaWindowActor` which has access to all the necessary bits to implement them. https://gitlab.gnome.org/GNOME/mutter/merge_requests/306
