And keep track of the hierarchy separately for the Wayland protocol and for output. Protocol state is updated immediately as protocol requests are processed, output state only when the corresponding transaction is applied (which may be deferred until the next commit of the parent surface). v2: * Directly add placement ops to a transaction, instead of going via pending_state. * Use transaction entry for the sub-surface instead of that for its parent surface. v3: * Use transaction entry for the parent surface again, to ensure proper ordering of placement ops, and call meta_wayland_surface_notify_subsurface_state_changed only once per parent surface. * Drop all use of wl_resource_add_destroy_listener, transactions are keeping surfaces alive as long as needed. v4: * Rebase on https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2501 * Drop ClutterActor code from meta_wayland_surface_apply_placement_ops. (Robert Mader) v5: * Rename MetaWaylandSubSurfaceState to MetaWaylandSurfaceSubState, since the next commit adds not sub-surface specific state to it. v6: * Move include of meta-wayland-subsurface.h from meta-wayland-transaction.c to .h, since the latter references MetaWaylandSubsurfacePlacementOp. v7: * Drop superfluous !entry check from meta_wayland_transaction_apply. v8: * Rename output/protocol fields to output/protocol_state. (Jonas Ådahl) v9: * Use meta_wayland_surface_state_new in meta_wayland_transaction_add_placement_op. v10: * Fix a few style issues per check-style.py.
