Class of graphics context.

Graphics context must implement this trait to be able to be used throughout the rest of the crate.

Associated Types

type Backend: ?Sized

Internal type used by the backend to cache, optimize and store data. This roughly represents the GPU data / context a backend implementation needs to work correctly.
