Updated `matrix.copy` to `applyMatrix`
When trying to pass in a Matrix4 via the matrix prop, it seemed that my Object3D wasn't applying it at all. After updating it to use applyMatrix, the matrix transformation seemed to work fine.
@toxicFork I submitted this pull request, however I saw that the old code used this function and then it was changed in January with this commit: https://github.com/toxicFork/react-three-renderer/commit/81142f8bbc17fd3d7509ba772814215da7f20765#diff-77134061d2e13d41e19e16ed94cf8cf6
Is there a reason this was changed from applyMatrix to the copy/decompose method? The latter doesn't work for me, hence the need for this PR.
Thanks!
I still need to investigate this (sorry about taking so long)
