- Made a bunch of changes to comply with Godot 4 API - Use Godot's Vector3i and add the missing stuff with helper functions - Transvoxel uses custom attributes API, the old way would not work - Wrap MeshOptimizer in a unique namespace (see build script why) - Added clang-format file for the module as some rules now differ - Prevent thirdparty code and lookup tables from being clang-formatted - Very likely full of runtime bugs that need fixing
