/// CEF supports both a Chrome runtime (based on the Chrome UI layer) and an

/// Alloy runtime (based on the Chromium content layer). The Chrome runtime

/// provides the full Chrome UI and browser functionality whereas the Alloy

/// runtime provides less default browser functionality but adds additional

/// client callbacks and support for windowless (off-screen) rendering. For

/// additional comparative details on runtime types see

/// https://bitbucket.org/chromiumembedded/cef/wiki/Architecture.md#markdown-header-cef3

///

/// Each runtime is composed of a bootstrap component and a style component. The

/// bootstrap component is configured via CefSettings.chrome_runtime and cannot

/// be changed after CefInitialize. The style component is individually

/// configured for each window/browser at creation time and, in combination with

/// the Chrome bootstrap, different styles can be mixed during runtime.

///

/// Windowless rendering will always use Alloy style. Windowed rendering with a

/// default window or client-provided parent window can configure the style via

/// CefWindowInfo.runtime_style. Windowed rendering with the Views framework can

/// configure the style via CefWindowDelegate::GetWindowRuntimeStyle and

/// CefBrowserViewDelegate::GetBrowserRuntimeStyle. Alloy style Windows with the

/// Views framework can host only Alloy style BrowserViews but Chrome style

/// Windows can host both style BrowserViews. Additionally, a Chrome style

/// Window can host at most one Chrome style BrowserView but potentially

/// multiple Alloy style BrowserViews. See CefWindowInfo.runtime_style

/// documentation for any additional platform-specific limitations.
