This is possible, if the option "aiProcess_ValidateDataStructure" is deactivated as postprocessing step, but the option "aiProcess_FindDegenerates" is activated and the mesh contains invalid data structures

* Make color single precision
* Fix the unittests for double precision
* Fix merge issues
* Fix issues with Vertex + Color4
* Fix vertex operator, some tests are still red.
* Squash development commits for PR
* Fix failing build on armeabi-v7a via android NDK
* Update with blendshape support
* Migrate to auto-cloning and patching tinyusdz (instead of manually copying files)
* Update to latest rendermesh-refactor branch commit
* Remove tracked file
* Update to use recent commit to "dev" branch
"rendermesh-refactor" was merged to "dev" around 9 May 2024 but merge
was not obvious from commit messages
* Add UNUSED() macro
(cherry picked from commit d89fe8f034c353cc5cc5b3ac78cd8845e006de38)
* Update tinyusdz branch
* Prevent per-ABI (x86, x86_64 etc) clone on android
* Add verbose logging cmake option
* Fix macro and patch
* Address compiler warnings
* Address compiler warnings
* Address compiler warnings
* Attempt prevent re-clone/re-patch once downloaded by any ABI build
* Disable tinyusdz clone/build by default
assimp github PR auto-CI checks clone/build the tinyusdz code, and reject PR
due to compiler warnings in the 3rd party external tinyusdz project

This commit fixes some bool loads which are not initialized. With ubsan and the "option -fsanitize=bool", this results in a runtime error during test execution.

* 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

Allows to export unlimited (more than 4) bones per vertex
Use JOINTS_1,2,.. and WEIGHTS_1,2,...
Added AI_CONFIG_EXPORT_GLTF_UNLIMITED_SKINNING_BONES_PER_VERTEX flag
The omitted vertex colors are treated as (0, 0, 0, 1).
