Tested:
$ cmake -DASSIMP_DOUBLE_PRECISION=1 -DASSIMP_BUILD_MDL_IMPORTER=0 ..; make
The MDL importer is disabled due to the fact that there is some float-only code
in MDL. This also means bin/assimp and bin/unit would not link successfully with
the above build flags.
There's a code path where an input scene only has a single mesh.
In this case, if ProcessMesh returns 2, we delete the mesh and move on
with the postprocessing. UpdateMeshReferences is not called and so the
deleted mesh is left dangling in nodes.
In a later step (SplitMesh in my testing), it then tries to deference a
null pointer and we explode.
With `out = true`, we can now hit the DeadlyImportError instead of a
segfault.
In debug builds, there's no issues, but in release, an invalid mesh that
is deleted in FindInvalidDataProcess will be double free'd when the
parent scene is destroyed.
- Moved TextureTypeToString to it's own file.
- Added new file to CMakeLists.txt.
- Added 6 missing values in TextureTypeToString.
- Added 6 missing aiTextureType enum values in assimp_cmd/Info.cpp.

Fixes flip to backfacing in models that mirrored some nodes.
