Add a debanding property to Viewport
It can be enabled in the Project Settings
(`rendering/quality/screen_filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).
It will also slightly brighten the scene's dark areas.

As a result, it should be enabled only when banding is noticeable enough.

This closes #17006.

George Marques 2b9d9bc364
Remove multilevel calls
In general they are more confusing to users because they expect
inheritance to fully override parent methods. This behavior can be
enabled by script writers using a simple super() call.

Rémi Verschelde 0ee0fa42e6 Style: Enforce braces around if blocks and loops
Using clang-tidy's `readability-braces-around-statements`.

Rémi Verschelde 07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.

Part of #33027.

Rémi Verschelde 0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

Rémi Verschelde e956e80c1f Style: clang-format: Disable AllowShortIfStatementsOnASingleLine
Part of #33027, also discussed in #29848.

Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.

Turn the anisotropic filtering setting into an enum
Since it only accepts power-of-two values, exposing it as an enum
makes more sense. This also allows for adding property hints to indicate
the performance cost of each value.

This also improves property hints for MSAA and FXAA.

Rémi Verschelde fdf58a5858 Rename InputFilter back to Input
It changed name as part of the DisplayServer and input refactoring
in #37317, with the rationale that input no longer goes through the
main loop, so the previous Input singleton now only does filtering.

But the gains in consistency are quite limited in the renaming, and
it breaks compatibility for all scripts and tutorials that access
the Input singleton via the scripting language. A temporary option
was suggested to keep the scripting singleton named `Input` even if
its type is `InputFilter`, but that adds inconsistency and breaks C#.

Fixes godotengine/godot-proposals#639.
Fixes #37319.
Fixes #37690.

Rémi Verschelde cb282c6ef0 Style: Set clang-format Standard to Cpp11
For us, it practically only changes the fact that `A<A<int>>` is now
used instead of the C++03 compatible `A<A<int> >`.

Note: clang-format 10+ changed the `Standard` arguments to fully
specified `c++11`, `c++14`, etc. versions, but we can't use `c++17`
now if we want to preserve compatibility with clang-format 8 and 9.
`Cpp11` is still supported as deprecated alias for `Latest`.

Fabio Alessandrelli b8ddaf9c33 Refactor ScriptDebugger.
EngineDebugger is the new interface to access the debugger.
It tries to be as agnostic as possible on the data that various
subsystems can expose.

It allows 2 types of interactions:

- Profilers:
  A subsystem can register a profiler, assigning it a unique name.
  That name can be used to activate the profiler or add data to it.
  The registered profiler can be composed of up to 3 functions:
    - Toggle: called when the profiler is activated/deactivated.
    - Add: called whenever data is added to the debugger
      (via `EngineDebugger::profiler_add_frame_data`)
    - Tick: called every frame (during idle), receives frame times.

- Captures: (Only relevant in remote debugger for now)
  A subsystem can register a capture, assigning it a unique name.
  When receiving a message, the remote debugger will check if it starts
  with `[prefix]:` and call the associated capture with name `prefix`.

Port MultiplayerAPI, Servers, Scripts, Visual, Performance to the new
profiler system.

Port SceneDebugger and RemoteDebugger to the new capture system.
The LocalDebugger also uses the new profiler system for scripts
profiling.

Rémi Verschelde f742dabafe Signals: Manually port most of remaining connect_compat uses
It's tedious work...

it's a class inherited by the current one).

Juan Linietsky 33b5c57199 Variant: Added 64-bit packed arrays, renamed Variant::REAL to FLOAT.
- Renames PackedIntArray to PackedInt32Array.
- Renames PackedFloatArray to PackedFloat32Array.
- Adds PackedInt64Array and PackedFloat64Array.
- Renames Variant::REAL to Variant::FLOAT for consistency.

Packed arrays are for storing large amount of data and creating stuff like
meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of
memory. That said, many users requested the ability to have 64 bits packed
arrays for their games, so this is just an optional added type.

For Variant, the float datatype is always 64 bits, and exposed as `float`.

We still have `real_t` which is the datatype that can change from 32 to 64
bits depending on a compile flag (not entirely working right now, but that's
the idea). It affects math related datatypes and code only.

Neither Variant nor PackedArray make use of real_t, which is only intended
for math precision, so the term is removed from there to keep only float.

Rémi Verschelde 49fec646cb Fix compilation warnings and re-enable werror=yes on Travis
Fix -Wunused-variable, -Wunused-but-set-variable and -Wswitch warnings
raised by GCC 8 and 9.

Fix -Wunused-function, -Wunused-private-field and
-Wtautological-constant-out-of-range-compare raised by Clang.

Fix MSVC 2019 warning C4804 (unsafe use of type 'bool' in comparison
operation).

GCC -Wcpp warnings/Clang -W#warnings (`#warning`) are no longer raising
errors and will thus not abort compilation with `werror=yes`.

Treat glslang headers are system headers to avoid raising warnings.

Re-enables us to build with `werror=yes` on Linux and macOS, thus
catching warnings that would be introduced by new code.

Fixes #36132.

Erik 8b0546d93b Implement game camera override
Implemented uniform API in Viewport class to override 2D and/or
3D camera.

Added buttons in 2D and 3D editor viewport toolbars that override
the running game camera transform with the editor viewport camera
transform. Implemented via remote debugger protocol and camera
override API.

Removed LiveEditFuncs function pointers from ScriptDebugger class.
Since the debugger got access to the SceneTree instance (if one
exists), there is no need to store the function pointers. The live
edit functions in SceneTree are used directly instead. Also removed
the static version of live edit functions in SceneTree for the same
reason. This reduced the SceneTree -> Debugger coupling too since
the function pointers don't need to be set from SceneTree anymore.

Moved script_debugger_remote.h/cpp from 'core/' to 'scene/debugger/'.
This is because the remote debugger is now using SceneTree directly
and 'core/' classes should not depend on 'scene/' classes.

PouleyKetchoupp 1a9801f700 Fixed leak on exit when using yield with SceneTreeTimer
Use case:
yield(get_tree().create_timer(2), "timeout")

Some resources were never released because the SceneTreeTimer was keeping a reference to GDScriptFunctionState in its signal connections, while GDScriptFunctionState was holding a reference to the SceneTreeTimer object. Cleaning all signal connections on game exit fixes the issue.

Hein-Pieter van Braam 0e29f7974b Reduce unnecessary COW on Vector by make writing explicit
This commit makes operator[] on Vector const and adds a write proxy to it.  From
now on writes to Vectors need to happen through the .write proxy. So for
instance:

Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;

Failing to use the .write proxy will cause a compilation error.

In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.

_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.

Fabio Alessandrelli 348725dfe0 Add option to disable automatic multiplayer poll
Automatic poll from SceneTree is enabled by default.
This allows for polling (and thus RPCs/RSETs) manually in other loops
(e.g. physics, thread, specific step) and for proper mutex protecion
when accessing the multiplayer API from threads (e.g. for sending larger
files in chunks).

Pedro J. Estébanez de9d40a953 Implement universal translation of touch to mouse
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)

The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.

Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.

*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.

On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.

Plus: Improve/fix tracking of current mouse position.

** Summary of changes to settings: **

- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
