scaleMat is always empty in ApplyTransform

[managerdark]

Hello, could you help me figure it out? As i can see scaleMat is always empty and never changes. https://github.com/binzume/modelconv/blob/3b9b77f43e6d2f035d17db8cb865908974acef44/gltfutil/gltf_utils.go#L85-L86

Because of this, almost all code does nothing. And model transforms incorrectly. Could you say what wrong with it? I tried to use transformMat without transition (and some other combinations), but it doesn't work too.
