Make copy and pasting match duplication's ownership transferral behavior by storing ownership information in the duplicated nodes on the node clipboard, then checking that information when setting owners for pasted nodes.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Adds "Filter by Type" and "Filter by Group" in the Scene Tree Dock's MenuButton.
Hovering on them displays an useful tooltip.
When selecting these items, the matching parameter is appended to the terms, and the caret is automatically brought to the end.
When typing a filter that cannot be identified, a warning icon is displayed. The reason is explained as a tooltip.
The same options are also quickly available by right-clicking or middle-clicking in the text field.
The shortcut's name is "scene_tree/toggle_unique_name", not mapped to anything by default.
It also dynamically changes the text based on whether or not the unique name is going to be enabled or disabled.
Finally, it spaces the shortcut in the menu close to "Copy Node Path" if possible.
Removes separate `Command` key (use `Meta` instead).
Adds an event flag to automatically remap `Command` <-> `Control` (cannot be set alongside `Control` or `Meta`).
Affects a lot of classes. Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on.
Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency.
Just a few comments have also been changed to say "redraw".
In CPUParticles2D, there was a private variable with the same name. It has been renamed to `do_redraw`.
