It's a somewhat general 3D API wrapper which exposes an API that's similar to Metal and WebGPU, but with a number of restrictions because it needs to support GLES2/WebGL backends as the worst case).

One idea I'm playing with is to provide callback hooks so that resource allocation and management can be delegated to the API user (so they can for instance integrate VMA themselves), and only provide a rudimentary default solution (which probably would be enough for many simple use cases).
