* 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

When loading a mesh exported from assimp into Blender, it warns that it has an incorrect class.
While debugging, I traced it back to this being `Blendshape` where `Geometry` was expected. This
is likely because this node describes a `Geometry`, which is used as a blendshape. I'm not sure
if any other DCC tools or places to import it expect `Blendshape` instead (i.e. was this code
ever tested?), but it fixes its use in Blender.

The previous table was in an incorrect order, leading to index references in DXF producing the wrong colours when converted.
Also added other entries to bring the total number of ACI colours up to the number that can be used in DXF files
Changed order of operations for insert positioning and scaling. Need to position the inserts before scaling it, otherwise the position ends up up being position*scale
Currently, when the coordIndex attribute of an IndexedLineSet contains a
polyline with > 2 indices, X3DGeoHelper::coordIdx_str2faces_arr() will
incorrectly determine the primitive type to be aiPrimitiveType_TRIANGLE or
aiPrimitiveType_POLYGON instead of aiPrimitiveType_LINE.
To fix this, this commit adds functions to explicitly handle an IndexedLineSet.
Fixes#3101
The regression was introduced in 904f17f.
Since all the cases are now fully handled at the child level,
visiting the whole subtree is changed into iteration over the children.
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.
