// http://dev.chromium.org/blink/runtime-enabled-features // // This list is used to generate RuntimeEnabledFeatures.h/cpp which contains // a class that stores static enablers for all experimental features. // // Each feature can be assigned a "status": // status=stable -> Enable this in all Blink configurations. We are committed to these APIs indefinitely. // status=experimental -> In-progress features, Web Developers might play with, but are not on by default in stable. // status=test -> Enabled in ContentShell for testing, otherwise off. // status=deprecated -> Alias for "test", will be removed at some point. // Features without a status are not enabled anywhere by default. // // "stable" features listed here should be rare, as anything which we've shipped stable // can have its runtime flag removed soon after. // // condition=ENABLE_NAME is used for wrapping features in compile-time // #if ENABLE(FEATURE) guards.
