Previously, clicking the LMB while renaming an animation could cause
`SpriteFramesEditor::_update_library(false)` to be called during
`Tree::propagate_mouse_event()`. This may cause a crash.
We can defer updates to the editor interface to avoid calling
`Tree::create_item()` at the wrong time.
Enables `SpriteFramesEditor::_select_animation()` to be able to undo/redo
When the name suffix grows, the old name is used if it is obtained first.
Fix the case where the following error message would appear when renaming
an animation.
```
ERROR: Animation '' doesn't exist.
at: get_frame_count (scene/resources/sprite_frames.cpp:71)
```
Also start organizing editor-specific GUI components
into a dedicated folder, `editor/gui`.
Also move `editor_file_server` next to the rest of debugger classes.
* This solution is much cleaner than the one in 3.x thanks to the use of callables.
* Works without issues in any language (no need to worry about camel or snake case).
* Editor code uses a compatibility function (too much work to redo).
Fixes#59899
* All core types masks are now correctly marked as bitfields.
* The enum hacks in MouseButtonMask and many other types are gone. This ensures that binders to other languages non C++ can actually implement type safe bitmasks.
* Most bitmask operations replaced by functions in BitField<>
* Key is still a problem because its enum and mask at the same time. While it kind of works in C++, this most likely can't be implemented safely in other languages and will have to be changed at some point. Mostly left as-is.
* Documentation and API dump updated to reflect bitfields in core types.
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".
Somehow I missed the failing CI report from trailing whitespace.
Fixed a couple typos found by codespell while at it, and misc
trailing semicolons in one of the files.
