Port FBX module from commit 68013d23932688e57b489600f4517dd280edc464 Ports FBX module from 3.2 branch to 4.0 This is the only time the plugin will be updated from 3.2 and marks the final time we do this, from now on we will backport FBX to 3.2 with fixes. Changelog: - fixed crash importing files with buggy format (because of bad newlines in ASCII data, this is yet to be fixed fully) - fixed const correctness with C++/C version change - rewrote material handling to be simpler and better - ports from 3.2 to 4.0 the fbx importer

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 🎆

Port FBX module from commit 68013d23932688e57b489600f4517dd280edc464 Ports FBX module from 3.2 branch to 4.0 This is the only time the plugin will be updated from 3.2 and marks the final time we do this, from now on we will backport FBX to 3.2 with fixes. Changelog: - fixed crash importing files with buggy format (because of bad newlines in ASCII data, this is yet to be fixed fully) - fixed const correctness with C++/C version change - rewrote material handling to be simpler and better - ports from 3.2 to 4.0 the fbx importer
