1//! Rendering to the canvas of a view: the surface, its render targets (a
2//! WebGL context or a framebuffer copied to a 2D canvas), the render timer
3//! driven by the animation frames of the page or of a render worker, the
4//! render worker, and what the thread of the user interface and a render
5//! thread share about a canvas.
6//!
7//! By who holds what (`docs/porting/browser-render-worker.md`, section 4):
8//!
9//! - [`BrowserSurfaceShared`] is what both threads know about a canvas, and
10//!   [`BrowserRenderSurface`] the render surface over it that the compositor
11//!   is handed. Neither holds an object of a thread.
12//! - [`BrowserRenderTarget`] ([`BrowserWebGlRenderTarget`],
13//!   [`BrowserSoftwareRenderTarget`]) is the render target of a canvas on
14//!   the thread that draws to it, kept in a table of that thread
15//!   ([`get_render_target`]).
16//! - [`RenderTargetBrowserSurface`] is the surface of a view on the thread
17//!   of the user interface.
18//!
19//! Without a render thread the three live on the one thread of the page.
20//!
21//! With one ([`BrowserSharedRenderLoop::start_render_thread`], which the
22//! platform calls in a module built with threads) the compositor of a view
23//! is confined to it: the frame loop ticks there, the canvas of a view is
24//! transferred to its worker, and the thread of the user interface commits
25//! batches and waits. [`RenderStatistics`] is where the page reads which
26//! thread drew its frames.
