ClutterPickStack is a new boxed type that stores the vertices and clip rectangles. It is meant to be a byproduct of picking, and takes over most of what ClutterStage currently does. It introduces a 'seal' system, inspired by MetaKmsUpdate. After the pick operation is done, and the rectangles are collected, the pick stack is sealed, and is not allowed to be externally modified anymore. Internally, it still can invalidate pick records when an actor is destroyed. For now, it handles both the clip rectangles, and the matrix stack, separatedly. Future commits will rearrange this. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1509 |
