//! Description of the steps of the rendering process, and the images used as input or output.
//!
//! # Render passes and framebuffers
//!
//! There are two concepts in Vulkan:
//!
//! - A *render pass* describes the overall process of drawing a frame. It is subdivided into one
//!   or more subpasses.
//! - A *framebuffer* contains the list of image views that are attached during the drawing of
//!   each subpass.
//!
//! Render passes are typically created at initialization only (for example during a loading
//! screen) because they can be costly, while framebuffers can be created and destroyed either at
//! initialization or during the frame.
//!
//! Consequently you can create graphics pipelines from a render pass object alone.
//! A `Framebuffer` object is only needed when you actually add draw commands to a command buffer.
