// 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.
// Features without a status are not enabled anywhere by default.
//
// "implied_by" or "depends_on" specifies relationship to other features:
// implied_by=feature1[,feature2,...] -> The feature is automatically enabled if any implied_by features is enabled;
// depends_on=feature1[,feature2,...] -> The feature is enabled only if all depends_on features are enabled.
// Only one of "implied_by" and "depends_on" can be specified.
//
// "stable" features listed here should be rare, as anything which we've shipped stable
// can have its runtime flag removed soon after.
//
// origin_trial_feature_name=FEATURE_NAME is used to integrate the feature with the experimental framework, so that the
// feature can be enabled at runtime on a per-page basis through a signed token for the corresponding feature name.
// Declaring the origin_trial_feature_name will cause a static method to be generated in OriginTrials.h/cpp. This static
// method allows the feature implementation to check if it is enabled for the current context.
