  Physical based rendering with Vulkan using glTF 2.0 models

The code in Node::update() here https://github.com/SaschaWillems/Vulkan-glTF-PBR/blob/master/base/VulkanglTFModel.cpp seems to tank FPS when multiple nodes share the same skin during animation - if a skin has 100 joints and 30 nodes use the skin - that's 3000 node transformations per frame.

This function is the hot-path - at least with the RecursiveSkeletons sample. Anytime the program queries the transform matrix of a particular node, it reconstructs the entire transform chain of that node all the way to the root from the individual TRS representations.
