class Renderer

Renders using a compatible graphics context.

Does not own the display, presentation surface, resource provider, or mutable game state. render() consumes ordered passes from a published frame on the graphics thread. The operations below are backend primitives for the frame renderer. Borrowed frame/matrix inputs must remain stable through each call. The caller brackets native use with backend initialization/teardown and retains its context. A backend failure may leave native state changed or part of a frame drawn.
