258cdfd2bc Export tangents in GLTF (#5900) 
Previously tangents were not being exported. If they are present, they should also be properly
exported.

ca17cdc1f9 Do not create GLTF Mesh if no faces (#5878) 
Previously GLTF meshes were created even if there were no faces, which lead to GLTFs which were not technically valid.

I believe this fixes the problem I was encountering, but I've not been able to test it because of some Mac compile errors. Will test on a windows machine at some point.

Fixes #5868

2d98f6a880 Fix identity matrix check (#5445) 
* Fix identity matrix check

Adds an extra epsilon value to check the matrix4x4 identity. The method is also used to export to GLTF/GLTF2 format to check node transformation matrices. The epsilon value can be set using AI_CONFIG_CHECK_IDENTITY_MATRIX_EPSILON with the default value set to 10e-3f for backward compatibility of legacy code.

* Fix type of float values in the unit test

* Update matrix4x4.inl

Fix typo

* Update matrix4x4.inl

Remove dead code.

* Add isIdentity-Test

* Update AssimpAPITest_aiMatrix4x4.cpp

9efbbe0a69 Read int from uvwsrc 
Previously was reading a uint, which always failed. Since the output was never checked, this
seemed to work, and works fine for most models since they only use UV channel 0.

a2bdfdd05a Improve binary check for gltf and gltf2. 
By checking the magic token we don't depend on the extension any more
and follow the official way to detect a gltf file as binary, see also
