Investigate Babylon.js WebGPU speed-ups and camera improvements

[Abbondanzo]

Babylon.js has some powerful features and better bookkeeping than that of Three.js but it would be great to measure just how much more powerful the framework is. Track the following changes:

• Camera interpolation
• Object interpolation and animation keyframe builder ease-of-use
• Object-state management
• CPU vs. GPU performance
  • on paint
  • on camera changes
  • on initial load/render
• Model loading/loaders (ease-of-use)
• WebGPU vs WebGL main thread performance (any noticeable slowdown inside a heavy React app?)
