Reopened due to accidental branch deletion.

Need some CICD.

Alternative to #32218 that directly uses Godot's importer to write an exporter.

Features:

Export the scene to glTF2.

Updated 2020-12-20

Todo:

  • Blend shapes are broken

Done:

  • Extra nodes on the root. Debugged.
  • Transforms on textures
  • Renamed to import mesh node and import mesh
  • Add filtering for nans in min and max accessors.
  • Checked csg again
  • Robust compatibility with blender
  • Add lights
  • Move from the the tools menu to an export menu. Use this new plugin interface to add an "export scene" option.
  • Integrate new 4.0 apis
  • Fix alpha scissors
  • Support KHR_texture_transform https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_texture_transform
  • Remove duplicate AnimationPlayer node
  • Remove duplicate Skeleton node
  • Ignored UV Scaling [Not part of the core gltf2 spec] https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_texture_transform
  • Bone attachments Updated 2020-01-01 New Years!
  • Support GLB binary gltf exports
  • Support editor created animation properties
  • Remove extra node on roundtrip.
  • Meshes
  • CSG
  • Gridmap
  • Materials
  • Bone weights
  • Bones
  • Blendshapes
  • The root node is put under the new root node.
  • Cameras
  • Debugged skins and animation skeletons
  • More debugging of meshes
  • Material caching
  • Use node index instead of bone names to do child parent relationships
  • Support all meshes instead of just array meshes
  • Debugged crash with Gridmaps
  • Removed extra node under skeleton for the skeleton
  • Bone animations
  • Blend shape animations (2019-12-05)
  • Camera crashes (2019-12-06)

Special Thanks

Current questions:

@reduz

Round tripping Godot import and export adds nodes.

Need some advice on how to merge the 5-8 encode accessors types. The encode accessors code was mostly copy and paste.

How to add the exporter abstraction?

Another thing is creating the concept of an exporter that is lossy in the editor interface design. Like a menu?

Due to the requirement of requiring new import and export apis, this is definitely a 4.0 feature. It's back portable, but the pull request as it is currently will be changed.

Could you also amend the commit message to be more explicit? "Import and export GLTF2." is misleading as it sounds like it's implementing glTF 2.0 import, which is already supported.

I'd suggest adding some details to the commit message's body to explain what the commit actually implements (it doesn't have to be as thorough as the PR description, just a few lines that tell a git log reader what to expect from that commit).
