df18f72384 BVH fix pairing AABB init and mask checks
Fix bug whereby AABBs were reused from previous items due to use of a pool, resulting in missed collisions.
Also use full mask collision checks for all cases except generic update.

ba5e4d8baa BVH fix stale changed items, causing dangling pairs
In the octree collisions are flushed as objects are moved, whereas in the BVH they are usually flushed once per frame.

This was causing problems in the render tree in some rare situations where objects were being created (perhaps deleted and recreated using the same handle in the same frame). This PR flushes the collisions before creating objects, and set_pairable.

set_pairable may not be necessary but it is done for safety until proven not necessary.

Also a small potential for a bug is closed in remove_unordered use.

4954a869bb BVH render tree new updating scheme
Change render BVH update scheme from once per update_dirty_instances to a new update_scenarios function called once per draw.

Fix lights not being properly unpaired.
Fixed bug in add_changed_item where AABBs were not being updated due to more than one update per tick.

a241aeb289 Fix BVH set_pairable and masks.
Calling set_pairable now will update collisions (rather than waiting for the next item_move).

Mask behaviour used for pairing now (hopefully) matches octree.

112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

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 🎆

47899e67c5 Add ability to restore RandomNumberGenerator state
3.2 version of b5107715f1.

`get_seed()` still returns the previous state and not the initial seed,
because users may rely on this behavior for resetting the state in 3.2.
Documented this is going to be fixed in 4.0.

667c970b77 Optimize octree and fix octree leak
Prevents adding new octants until a limiting number of elements have been added to the current octant. This enables balancing the benefits of brute force against the benefits of spatial partitioning. The limit can be set per octree.

Project settings are added for rendering octree to set the best balance per project depending on number of tests per frame / tick, and the amount of editing of the octree.

Fixes octants being leaked when removing elements.

Optimize octree with cached linear lists

Storing elements in octants using linked lists is efficient for housekeeping but very slow for testing. This optimization stores additional local_vectors with Element pointers and AABBs which are cached and only updated when a dirty flag is set on the octant.

This is selectable with 2 versions of Octree : Octree and Octree_CL, Octree being the old behaviour. At present the cached list version is only used for the visual server octree (rendering) as it has only been demonstrated to be faster there so far.

This uses slightly more memory (probably a few kb in most cases) but can be significantly faster during testing (culling etc).

This reverts commit 7f61710183.

See #38868, in its current implementation a small skew value might end up
serialized to scene files due to floating point precision errors, which is
detrimental to VCS.

This can be cherry-picked anew once a fix for #38868 has been found.

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.

bac44ee19f Fixed false positives in the culling system.
This fixes numerous false positives coming out of the culling system.

AABB checks are now a full separating-axis check against the frustum, with the points of the frustum being compared to the planes of the box just as the points of the box were being compared to the planes of the frustum. This fixes large objects behind the camera not being culled correctly.

Some systems that used frustums that were (sometimes mistakenly?) unbounded on one or more side have been modified to be fully enclosed.

eaf8e5ce52 Change CameraMatrix::get_viewport_size to get_viewport_half_extents
Fixes #26637.
Fixes #19900.

The viewport_size returned by get_viewport_size was previously incorrect, being half the correct value. The function is renamed to get_viewport_half_extents, and now returns a Vector2.

Code which called this function has also been modified accordingly.

This PR also fixes shadow culling when using ortho cameras, because the correct input for CameraMatrix::set_orthogonal should be the full HEIGHT from get_viewport_half_extents, and not half the width.

It also fixes state.ubo_data.viewport_size in rasterizer_scene_gles3.cpp to be the width and the height of the viewport in pixels as stated in the documentation, rather than the current value which is half the viewport extents in worldspace, presumed to be a bug.

By incorrectly using -e/c instead of -d/a, Face3::get_closest_point_to was returning the wrong point in certain cases.  Specifically, I noticed it returning vertex[0] when it should have been returning vertex[1].

71d71d55b5 Replace 'ERR_EXPLAIN' with 'ERR_FAIL_*_MSG' in 'core/' and 'editor/'
Condensed some if and ERR statements. Added dots to end of error messages

Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)

d844e30614 Inspector: Make default float step configurable
Also allow lifting the decimal step formatting with a hint range step
of 0. A new `range_step_decimals()` is added for this to avoid breaking
compatibility on the general purpose `step_decimals()` (which still
returns 0 for an input step of 0).

Supersedes #25470.
Partial fix for #18251.
