That would be the easy part. From the post they are already stored as such, but the complexity would be to render the vector graphics in C++ at 60FPS. There is no simple solution to this, and rolling it yourself is quite the task too. If you look at some of the modern approaches to animation in C++ (like Lottie or Rive) their C++ clients are pretty poorly supported in my opinion, mostly for anti-aliasing quality in native clients over their web equivalents.
