clayjohn 51ed3aef63 Vertex and attribute compression to reduce the size of the vertex format.
This allows Godot to automatically compress meshes to save a lot of bandwidth.

In general, this requires no interaction from the user and should result in
no noticable quality loss.

This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.

Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.

Lyuma bc24d01359 gltf: Add GLTFHandleBinary::HANDLE_BINARY_EMBED_AS_UNCOMPRESSED
This option allows for a safe fallback for embedded gltf textures in cases where VRAM compression is not needed.
Add an is_editor_hint guard around GLTFHandleBinary::HANDLE_BINARY_EXTRACT_TEXTURES, to use EMBED_AS_UNCOMPRESSED by default at runtime.
This provides an option for pixel art to be stored losslessly.
Additionally, respect project importer defaults for texture import settings.
Avoid writing and reimporting extracted textures identical to version on disk.

K. S. Ernest (iFire) Lee 39922d7167 Handle gltf binary
[ Ignore and Warn | Extract Textures (default) | Optimize Loading Embedded as Basisu ]

Enable compressed mip maps from Basis Universal for faster compressions.

Increase the quality of Basis to avoid corruption.

To keep compatibility use the first mip of the previous internal Godot format.

Because texture names may have invalid filename characters, adds String::validate_filename to sanitize filenames for import pipeline use.

Lyuma 03bd1da32b Avoid nested skeletons, and handle skinned meshes with children.
Recursively adds child nodes into each skeleton. This should prevent nested skeletons and avoid bone attachments for leaf bones.

In cases where a skinned mesh has children, creates two scene nodes with the same name, which both will represent this single gltf node.
Because blend shape animations must target the mesh, adds a separate mapping for ImporterMeshInstance3D node references.

This change will break existing imported scenes with bone attachments and more than one skeleton.

One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

reduz 746dddc067 Replace most uses of Map by HashMap
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
  (order matters) but use is discouraged.

There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!

Convert GLTF Document to use ImporterMeshInstance3D.

Add a GLTFDocument extension list and an extension for converting the importer mesh instance 3d to mesh instance 3d.

Use GLTF module when the editor tools are disabled.

Modified the render server to be less restrictive on matching blend arrays and have more logging.

Misc bugs with multimesh.

Always index the meshes.

Lyuma 5ffda27ea9 gltf export: Fix export of skeletons, skins and blend shapes.
Create GLTFSkeleton at the same time we create GLTFNode objects.
Create GLTFSkin at the same time we export MeshInstance3D
Fixes export of blend shape arrays for meshes with multiple surfaces.
Fixes array indexing issues in export of glTF morph target animations.

Converts BoneAttachment3D nodes during normal node creation: this avoids
special cases during mesh export, and especially exporting skeletons or meshes
which are children of BoneAttachment3D.

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 🎆
