- StructureOfArray: don't initialize trivial ctors
We mimic the behavior of std::vector<> here, where a resize() won't
initialize the array if the type is trivially_default_constructible.
This can reveal existing bugs, where we depended on the initialization
to 0.
- StructureOfArray: add push_back(std::tuple<>)
This basically allows us to push_back() a struct of the SoA.
- Make PerRenderableData trivially constructible
this improves performance when we have tons of objects in the scene
because PerRenderableData is used in arrays.
