+//! Renderer implementation and utilities. The renderer is responsible for
+//! taking the internal screen state and turning into some output format,
+//! usually for a screen.
+//!
+//! The renderer is closely tied to the windowing system which usually
+//! has to prepare the window for the given renderer using system-specific
+//! APIs. The renderers in this package assume that the renderer is already
+//! setup (OpenGL has a context, Vulkan has a surface, etc.)
