The original logic was never called for certain platforms, leaving the
hide reason unset and causing weird semi-random issues with the few
users of that internal API, such as when renaming nodes in the scene
tree editor.
GLOBAL_GET is an expensive operation which should not be used each frame / tick.
This PR adds macros which do a cheaper revision check, and only call the expensive GLOBAL_GET when project settings have changed.

The backend is now mature enough to not explode with multiple windows
but the `DisplayServer` API still cannot meet some guarantees required
by the various Wayland protocols we use. To meet those guarantees this
patch adds three new elements to the DisplayServer API, with relative
handling logic for `Window` and `Popup` nodes:
- `WINDOW_EVENT_FORCE_CLOSE`, which tells a window to *forcefully*
close itself and ensure a proper cleanup of its references, as Wayland
enforces this behavior;
- `WINDOW_FLAG_POPUP_WM_HINT`, which explicitly declares a window as a
"popup", as Wayland enforces this distinction and heuristics are not
reliable enough;
- `FEATURE_SELF_FITTING_WINDOWS`, which signals that the compositor can
fit windows to the screen automatically and that nodes should not do
that themselves.
Given the size of this feature, this patch also includes various
`WaylandThread` reworks and fixes including:
- Improvements to frame wait logic, with fixes to various stalls and a
configurable (through a `#define`) timeout amount;
- A proper implementation of `window_can_draw`;
- Complete overhaul of pointer and tablet handling. Now everything is
always accumulated and handled only on each respective `frame` event.
This makes their logic simpler and more robust.
- Better handling of pointer leaving and pointer enter/exit event
sending;
- Keyboard focus tracking;
- More solid window references using IDs instead of raw pointers as
windows can be deleted at any time;
- More aggressive messaging to window nodes to enforce rects imposed by
the compositor.
`AcceptDialog`, `Popup` and `PopupMenu` no longer subscribe to
"window_input" signal, because that is only sent if it is not an
internal signal.
Instead they receive events in `_input_from_window`. They ensure that
the event is also propagated to their super-function, just like
previously the signals would be treated.
As opposed to hardcoding the escape key. Also removed such hardcoding in a few other places as well as a hardcoded enter key in one of the affected input fields.
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".
This reverts commit 4b817a565c.
Fixes#64988.
Fixes#64997.
This caused several regressions (#64988, #64997,
https://github.com/godotengine/godot/issues/64997#issuecomment-1229970605)
which point at a flaw in the current logic:
- `Control::NOTIFICATION_ENTER_TREE` triggers a *deferred* notification with
`NOTIFCATION_THEME_CHANGED` as introduced in #62845.
- Some classes use their `THEME_CHANGED` to cache theme items in
member variables (e.g. `style_normal`, etc.), and use those member
variables in `ENTER_TREE`, `READY`, `DRAW`, etc. Since the `THEME_CHANGE`
notification is now deferred, they end up accessing invalid state and this
can lead to not applying theme properly (e.g. for EditorHelp) or crashing
(e.g. for EditorLog or CodeEdit).
So we need to go back to the drawing board and see if `THEME_CHANGED` can be
called earlier so that the previous logic still works?
Or can we refactor all engine code to make sure that:
- `ENTER_TREE` and similar do not depend on theme properties cached in member
variables.
- Or `THEME_CHANGE` does trigger a general UI update to make sure that any
bad theme handling in `ENTER_TREE` and co. gets fixed when `THEME_CHANGE`
does arrive for the first time. But that means having a temporary invalid
(and possibly still crashing) state, and doing some computations twice
which might be heavy (e.g. `EditorHelp::_update_doc()`).
