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 🎆

15e57a0235 Remove buffer orphaning options project settings
These were only put in for the betas, in order to test hypotheses for stalling on Macs. It seems that most of the problems in the Mac editor have been solved by fixing the excessive redraw_requests.

As a result no one has reported any results from these options, but in future we will be able to refer users to try the beta versions, so there is no need to include them in the stable release. Indeed they are only likely to cause confusion.

7c4cf1c043 Batching - BackBuffer copy fix
For fixing a previous issue state.canvas_texscreen_used was reset to false at the start of each render_joined_item. This was causing a later shader that used SCREEN_TEXTURE to force recapturing the back buffer immediately prior to use, which we don't want.

This PR preserves the state across joined items, and also prevents joining of items that copy the back buffer as this may be problematic.

It turns out that the original issue that needed the line is now fixed, and the later issue is also fixed by removing it.

3c69377f10 2d Legacy - close vulnerabilities and more debug checks
While adding more debug checks to legacy renderer, I closed 2 types of vulnerabilities:

* TYPE_PRIMITIVE would previously read from uninitialized data if only specifying a single color
* Other legacy draw operations would fail in debug AFTER accessing out of bounds memory rather than before

Many calls to glBufferSubData are wrapped in a safe version which checks for out of bounds and exits the draw function if this is detected.

1394df3188 Prevent item joining with custom shaders using selected BUILTINs
Large FVF allows batching of many custom shaders, but should not join items which have shaders that utilize BUILTINs which would change for each item, because these will not be sent individually, and all joined items would wrongly use the values from the first joined item.

5c8f497a24 Add project settings to manually specify API usage
As a result of the GLES specifications being vague about best practice for how buffers should be used dynamically, different GPUs / platforms appear to have different preferences.

Mac in particular seems to have a number of problems in this area, and none of the rendering team uses Macs. So far we have relied on guesswork to choose the best usage, but in an attempt to pin this down, this PR begins to introduce manual selection of options for users to test their configurations.

f4cb88e232 Fix transforms in custom shaders using large FVF
In small batches using hardware transform, vertices would be drawn in incorrect positions due to the item transform being applied twice - once in the transform uniform, and once from the transform passed as a vertex attribute.

This PR alters the shader to ignore uniform transforms when using large FVF.

debda7f411 Reverting changes to legacy polys and generic prims
Due to my less than eagle-like view over these functions I had assumed they were passing in a single buffer input for the changes to make buffer uploading more efficient. They aren't, which is less than ideal.

So these particular changes should be reverted. When I have some more time I'll see whether the API for these calls can be changed, because as is the multiple glSubBufferData calls could be causing stalls on some hardware.

Add a debanding property to Viewport for GLES3
It can be enabled in the Project Settings
(`rendering/quality/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).

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

Since debanding requires a HDR viewport to work, it's only supported
in the GLES3 backend.

Don't apply lighting to objects when they have a lightmap texture and

674327b78f GLES3 fix normal map flipping with nvidia workaround
When not using TEXTURE_RECT path, flips have to sent via another method to the shader, to ensure that normal maps are correctly adjusted for direction. This PR adds an extra vertex attribute, LIGHT_ANGLE.

For nvidia workarounds, where the shader still has access to the final transform and extra matrix, the LIGHT_ANGLE can be 0 (no adjustment), 180 degrees for a horizontal flip, and negative indicates a vertical flip.

For batching path, the LIGHT_ANGLE can be used to directly specify the light angle for normal mapping, even when the final transform and extra matrix have been baked into vertex positions, so the same shader can be used for both.

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.
