Detailed Description

Backend-facing rendering layer shared by the four graphics backends.

The Renderer base class, the command queue, shaders, and GPU buffer types live here. Most of it is internal; the pieces a game touches are the opaque handle types carried by public resources such as Material and MeshHandle.
