21a24eb959 Most recently added current Camera2D takes precedence
The situation when multiple current Camera2Ds were in the scene was not dealt with. This could leave several cameras with their current bool set, and each competing to update the viewport scroll, in a random / accidental fashion.

This PR standardises the rule that the most recent current Camera2D added to the scene tree takes over the current status, and sets all other current cameras in the scene tree to non-current. This makes the bools correct, and also prevents the competition over viewport scroll.

Uncap the range for gravity and change the slider hints
There's not really a reason to cap the gravity amount, and we can also
give better hints for the range (for 3D, ±32 is much more sensible
than ±1024).

Tweak Camera2D editor line colors for better visibility
The new color for screen drawing was chosen to be easier to distinguish
from the 2D viewport limits.

This also makes lines less opaque when the Camera2D has the Current
property enabled. The increased line width is enough to spot the
camera easily, and the increased opacity on top of that felt obnoxious.

Core: Drop custom copymem/zeromem defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

cdf0ebfac7 Fix Joint2D/Joint node path reset on scene switch

bodies is under the joint in the scene tree.

b1e24597e7 Renaming rendering/2d project settings.
The rendering/quality/2d section of project settings is becoming considerably expanded in 3.2.4, and arguably was not the correct place for settings that were not really to do with quality.

3.2.4 is the last sensible opportunity we will have to move these settings, as the only existing one likely to break compatibility in a small way is `pixel_snap`, and given that the whole snapping area is being overhauled we can draw attention to the fact it has changed in the release notes.

Class reference is also updated and slightly improved.

`pixel_snap` is renamed to `gpu_pixel_snap` in the project settings and code to help differentiate from CPU side transform snapping.

847a37b196 Change 2d transform snapping from floor to round
Two common problems have emerged as a result of transform snapping:
1) Camera jitter with a camera following a snapped object
2) Pixel gaps between e.g. a platform and a player, where a platform rounds down and a player rounds up

Using round seems to greatly reduce problems due to camera jitter. It also may prove better for  pixel gaps because pixel art is often designed on a grid, so whole numbers are too expected, which are unstable with floor().

- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.

Fix collision shape update when changing shape properties
This change does two things:

1. Properly update the internal shape data using _update_in_shape_owner
when updating a shape (in 2D it was resetting one way collision)

2. Avoid unnecessary updates when calling set_shape with the same shape,
which happens each time a shape property is modified
(e.g shape.extents.x = ...)

Fixes #45090

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

Update body transforms on joint2D setup
Body transforms from physics are used to setup the joint and they are

Without forcing the transform update, joints could use a previous

3D physics is not affected by this issue.

mat2 rotm;
rotm[0] = texelFetch(emission_texture_normal, emission_tex_ofs, 0).xy;
rotm[1] = rotm[0].yx * vec2(1.0, -1.0);
VELOCITY.xy = rotm * VELOCITY.xy;

Now both CPUParticles2D & CPUParticles3D (z disabled) show the same results
as their GPU counterparts and take the initial velocity settings into account.

7bf9787921 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

7f61710183 Implement Skew in Node2D
Skew is x-axis only, because it must be bidirectionally convertible to a 2x3 matrix, but you can subtract it  to the rotation to get the effect on y-axis

9af4c09d1b Fix uninitialized memory in CPUParticles2D
Calls to set_amount can increase the size of the particle array, but do not zero the memory, they only set the active flag to false. This uninitialized memory can be sent to the GPU, possibly as NaNs.

e70e0d24d9 Fix inverted use of Camera2D.offset_v
The code above for horizontal movement uses the right margin (_positive_ x direction) when the offset is negative, but vertical movement uses the top margin (_negative_ y direction) when the offset is negative.

The resulting problem is easily seen in the editor — set the drag margins to be asymmetrical, turn on drawing the drag margins, and slide the offsets from -1 to 1 and back.  The horizontal offset moves the camera's center between the left and right margins, but the vertical offset gets them backwards and will move the camera outside the margins entirely.

ba177ccaec doc: Misc updates for AnimationNode* and others
- Add some missing descriptions.
- Add links to tutorials for ARVR and AnimationTree.
- Style fixes.
- Engine changes:
  * Make `AnimationNodeTransition.input_<number>` properties internal
    so that they don't appear in the docs. They still appear in the
    inspector based on the actual number of inputs requested.
  * Drop unimplemented `CPUParticles.flatness`. It's only used for 3D
    particles in `ParticlesMaterial`, and thus only relevant for
    `CPUParticles3D`.
