This caused https://github.com/facebookincubator/FBX2glTF/issues/218
in ways that I honestly don't fully understand, and I believe only under
Windows, with Release-level optimisation turned on.
It's possible we should drop all these initializer lists, and replace
them with simple and explicit initialising constructors.
Fixes#218.
At the end of the various material/mesh transformations we do, we were still using a ridiculously simplistic method of mapping RawMaterial to glTF MaterialData.
This switches to using FBX's GetUniqueID(), which should be the law of the land in general. Other model entities may need further investigation as well.
This finishes the first phase of the FBX2glTF refactor, breaking utility classes out where things were getting too monolithic.
There is an equally important cleanup phase coming where we wrench all the various parts of this code, including the historical ones that we've rarely touched as yet, into a single C++ style paradigm, and modernise everything to C++11 at least.
But for now, we're just picking the pieces back on the floor so we can push 0.9.6 out. It's been far too long since a release.
Did not mean to commit/push the current state of master. But rather than
mess up source control history with a force push, I'll just try to hurry
to a stable point.
