* Safe and unsafe motion are calculated by dichotomy with a limited
number of steps. It's good for performance, but on long motions that
either collide near the beginning or near the end, the result can be
very imprecise.
* Now a factor 0.25 or 0.75 is used to converge faster when this case
happens, which allows longer motions to get more accurate collision
detection.
* Makes snap collision more precise, and helps with cases where diagonal collision on the border of a platform can lead to the character being stuck.
Additional improvements to move_and_slide:
* Handle slide canceling in move_and_collide with 0 velocity instead of
not applying it.
* Better handling of snap with custom logic to cancel sliding.
* Remove small jittering when using stop on slope, by canceling the
motion completely when the resulting motion is less than margin instead
of always projecting to the up direction (in both body motion and snap).

Make sure the direction of the motion is preserved, unless the depth is
higher than the margin, which means the body needs depenetration in any
direction.
Also changed move_and_slide to avoid sliding on the first motion, in
order to avoid issues with unstable position on ground when jumping.

Fixing by applying the movement in two steps, first the platform
movement, and then the body movement. Plus, add the platform movement
when we are on_wall.
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.
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.

Decide whether half offset should be added based on the value used for calculating the return value of this method.

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.
Backport of #48239.
When AnimatedSprite2D::play() was called before SpriteFrames has been initialized, a crach occurred (issue #46013).
Modification : An error message on null check test has been added to prevent crash.
Fix#46013.

The logic for internal process and internal physics process in Camera2D was very buggy and convoluted for historical reasons.
This is a cleanup to make the logic simpler and easier to follow.
More work is needed to make sure that those options actually solve users' issues, so we prefer to remove the options for 3.2.4 and revisit for a future release.
If true, collision shapes are shown in the editor and at run-time.
Requires Visible Collision Shapes to be enabled in the Debug menu,
for collision shapes to be visible at run-time.
When one of the bodies exited the tree, the corresponding node path was
reset instead of just resetting the joint from the physics server. That
was causing the node path to be reset on scene switch when one of the
bodies is under the joint in the scene tree.
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.
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().
