 # Introduction
@@ -24,15 +25,15 @@ CEF is a BSD-licensed open source project founded by Marshall Greenblatt in 2008
 
 CEF supports a wide range of programming languages and operating systems and can be easily integrated into both new and existing applications. It was designed from the ground up with both performance and ease of use in mind. The base framework includes C and C++ programming interfaces exposed via native libraries that insulate the host application from Chromium and Blink implementation details. It provides close integration between the browser and the host application including support for custom plugins, protocols, JavaScript objects and JavaScript extensions. The host application can optionally control resource loading, navigation, context menus, printing and more, while taking advantage of the same performance and HTML5 technologies available in the Google Chrome Web browser.
 
-Users new to CEF development should start by reading the [Tutorial](https://bitbucket.org/chromiumembedded/cef/wiki/Tutorial) Wiki page for an overview of CEF usage and then proceed to the [GeneralUsage](https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage) Wiki page for a more in-depth discussion or architectural and usage issues. Complete API documentation is available [here](http://magpcss.org/ceforum/apidocs3/). CEF support and related discussion is available on the [CEF Forum](http://www.magpcss.org/ceforum/).

 Numerous individuals and organizations contribute time and resources to support CEF development, but more involvement from the community is always welcome. This includes support for both the core CEF project and external projects that integrate CEF with additional programming languages and frameworks (see the "External Projects" section below). If you are interested in donating time to help with CEF development please see the "Helping Out" section below. If you are interested in donating money to support general CEF development and infrastructure efforts please visit the [CEF Donations](http://www.magpcss.org/ceforum/donate.php) page.
 
+# Getting Started
+
+Users new to CEF development should start by reading the [Tutorial](https://bitbucket.org/chromiumembedded/cef/wiki/Tutorial) Wiki page for an overview of CEF usage and then proceed to the [GeneralUsage](https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage) Wiki page for a more in-depth discussion or architectural and usage issues. Complete API documentation is available [here](http://magpcss.org/ceforum/apidocs3/). CEF support and related discussion is available on the [CEF Forum](http://www.magpcss.org/ceforum/).

 # Binary Distributions
 
-Binary distributions, which include all files necessary to build a CEF-based application, are available on the [Downloads](http://www.magpcss.net/cef_downloads/) page. Automated nightly builds, available from http://cefbuilds.com, include the newest changes but may not be fully tested. Binary distributions are stand-alone and do not require the download of CEF or Chromium source code. Symbol files for debugging binary distributions of libcef can also be downloaded from the above links.

-Release notes for past and current CEF binary distributions are available [here](https://bitbucket.org/chromiumembedded/cef/wiki/ReleaseNotes).

 The base CEF framework includes support for the C and C++ programming languages. Thanks to the hard work of external maintainers CEF can integrate with a number of other programming languages and frameworks. These external projects are not maintained by CEF so please contact the respective project maintainer if you have any questions or issues.

 //
+// For a runnable object of n-arity, the base::Bind*() family allows partial
+// application of the first m arguments. The remaining n - m arguments must be
+// passed when invoking the callback with Run().
+//
+//   // The first argument is bound at callback creation; the remaining
+//   // two must be passed when calling Run() on the callback object.
+//   base::OnceCallback<long(int, long)> cb = base::BindOnce(
+//       [](short x, int y, long z) { return x * y * z; }, 42);
+//
+// When binding to a method, the receiver object must also be specified at
+// callback creation time. When Run() is invoked, the method will be invoked on
+// the specified receiver object.
+//
+//   class C : public base::RefCounted<C> { void F(); };
+//   auto instance = base::MakeRefCounted<C>();
+//   auto cb = base::BindOnce(&C::F, instance);
+//   std::move(cb).Run();  // Identical to instance->F()

 // Implementation notes
 // -----------------------------------------------------------------------------
 //
 // If you're reading the implementation, before proceeding further, you should
-// read the top comment of base/bind_internal.h for a definition of common
-// terms and concepts.
-//
-// RETURN TYPES
-//
-// Though Bind()'s result is meant to be stored in a Callback<> type, it
-// cannot actually return the exact type without requiring a large amount
-// of extra template specializations. The problem is that in order to
-// discern the correct specialization of Callback<>, Bind would need to
-// unwrap the function signature to determine the signature's arity, and
-// whether or not it is a method.
-//
-// Each unique combination of (arity, function_type, num_prebound) where
-// function_type is one of {function, method, const_method} would require
-// one specialization.  We eventually have to do a similar number of
-// specializations anyways in the implementation (see the Invoker<>,
-// classes).  However, it is avoidable in Bind if we return the result
-// via an indirection like we do below.
-//
-// TODO(ajwong): We might be able to avoid this now, but need to test.
-//
-// It is possible to move most of the COMPILE_ASSERT asserts into BindState<>,
-// but it feels a little nicer to have the asserts here so people do not
-// need to crack open bind_internal.h.  On the other hand, it makes Bind()
-// harder to read.

-// This defines a set of argument wrappers and related factory methods that
-// can be used specify the refcounting and reference semantics of arguments
-// that are bound by the Bind() function in base/bind.h.
-//
-// It also defines a set of simple functions and utilities that people want
-// when using Callback<> and Bind().
-//
-//
-// ARGUMENT BINDING WRAPPERS
-//
-// The wrapper functions are base::Unretained(), base::Owned(), base::Passed(),
-// base::ConstRef(), and base::IgnoreResult().
-//
-// Unretained() allows Bind() to bind a non-refcounted class, and to disable
-// refcounting on arguments that are refcounted objects.
-//
-// Owned() transfers ownership of an object to the Callback resulting from
-// bind; the object will be deleted when the Callback is deleted.
-//
-// Passed() is for transferring movable-but-not-copyable types (eg. scoped_ptr)
-// through a Callback. Logically, this signifies a destructive transfer of
-// the state of the argument into the target function.  Invoking
-// Callback::Run() twice on a Callback that was created with a Passed()
-// argument will CHECK() because the first invocation would have already
-// transferred ownership to the target function.
-//
-// ConstRef() allows binding a constant reference to an argument rather
-// than a copy.
-//
-// IgnoreResult() is used to adapt a function or Callback with a return type to
-// one with a void return. This is most useful if you have a function with,
-// say, a pesky ignorable bool return that you want to use with PostTask or
-// something else that expect a Callback with a void return.
-//
-// EXAMPLE OF Unretained():
-//
-//   class Foo {
-//    public:
-//     void func() { cout << "Foo:f" << endl; }
-//   };
-//
-//   // In some function somewhere.
-//   Foo foo;
-//   Closure foo_callback =
-//       Bind(&Foo::func, Unretained(&foo));
-//   foo_callback.Run();  // Prints "Foo:f".
-//
-// Without the Unretained() wrapper on |&foo|, the above call would fail
-// to compile because Foo does not support the AddRef() and Release() methods.
-//
-//
-// EXAMPLE OF Owned():
-//
-//   void foo(int* arg) { cout << *arg << endl }
-//
-//   int* pn = new int(1);
-//   Closure foo_callback = Bind(&foo, Owned(pn));
-//
-//   foo_callback.Run();  // Prints "1"
-//   foo_callback.Run();  // Prints "1"
-//   *n = 2;
-//   foo_callback.Run();  // Prints "2"
-//
-//   foo_callback.Reset();  // |pn| is deleted.  Also will happen when
-//                          // |foo_callback| goes out of scope.
-//
-// Without Owned(), someone would have to know to delete |pn| when the last
-// reference to the Callback is deleted.
-//
-//
-// EXAMPLE OF ConstRef():
-//
-//   void foo(int arg) { cout << arg << endl }
-//
-//   int n = 1;
-//   Closure no_ref = Bind(&foo, n);
-//   Closure has_ref = Bind(&foo, ConstRef(n));
-//
-//   no_ref.Run();  // Prints "1"
-//   has_ref.Run();  // Prints "1"
-//
-//   n = 2;
-//   no_ref.Run();  // Prints "1"
-//   has_ref.Run();  // Prints "2"
-//
-// Note that because ConstRef() takes a reference on |n|, |n| must outlive all
-// its bound callbacks.
-//
-//
-// EXAMPLE OF IgnoreResult():
-//
-//   int DoSomething(int arg) { cout << arg << endl; }
-//
-//   // Assign to a Callback with a void return type.
-//   Callback<void(int)> cb = Bind(IgnoreResult(&DoSomething));
-//   cb->Run(1);  // Prints "1".
-//
-//   // Prints "1" on |ml|.
-//   ml->PostTask(FROM_HERE, Bind(IgnoreResult(&DoSomething), 1);
-//
-//
-// EXAMPLE OF Passed():
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) { }
-//   scoped_ptr<Foo> CreateFoo() { return scoped_ptr<Foo>(new Foo()); }
-//
-//   scoped_ptr<Foo> f(new Foo());
-//
-//   // |cb| is given ownership of Foo(). |f| is now NULL.
-//   // You can use f.Pass() in place of &f, but it's more verbose.
-//   Closure cb = Bind(&TakesOwnership, Passed(&f));
-//
-//   // Run was never called so |cb| still owns Foo() and deletes
-//   // it on Reset().
-//   cb.Reset();
-//
-//   // |cb| is given a new Foo created by CreateFoo().
-//   cb = Bind(&TakesOwnership, Passed(CreateFoo()));
-//
-//   // |arg| in TakesOwnership() is given ownership of Foo(). |cb|
-//   // no longer owns Foo() and, if reset, would not delete Foo().
-//   cb.Run();  // Foo() is now transferred to |arg| and deleted.
-//   cb.Run();  // This CHECK()s since Foo() already been used once.
-//
-// Passed() is particularly useful with PostTask() when you are transferring
-// ownership of an argument into a task, but don't necessarily know if the
-// task will always be executed. This can happen if the task is cancellable
-// or if it is posted to a MessageLoopProxy.
-//
-//
-// SIMPLE FUNCTIONS AND UTILITIES.
-//
-//   DoNothing() - Useful for creating a Closure that does nothing when called.
-//   DeletePointer<T>() - Useful for creating a Closure that will delete a
-//                        pointer when invoked. Only use this when necessary.
-//                        In most cases MessageLoop::DeleteSoon() is a better
-//                        fit.

-// http://stackoverflow.com/questions/1966362/sfinae-to-check-for-inherited-member-functions
-//
-// The last link in particular show the method used below.
-//
-// For SFINAE to work with inherited methods, we need to pull some extra tricks
-// with multiple inheritance.  In the more standard formulation, the overloads
-// of Check would be:
-//
-//   template <typename C>
-//   Yes NotTheCheckWeWant(Helper<&C::TargetFunc>*);
-//
-//   template <typename C>
-//   No NotTheCheckWeWant(...);
-//
-//   static const bool value = sizeof(NotTheCheckWeWant<T>(0)) == sizeof(Yes);
-//
-// The problem here is that template resolution will not match
-// C::TargetFunc if TargetFunc does not exist directly in C.  That is, if
-// TargetFunc in inherited from an ancestor, &C::TargetFunc will not match,
-// |value| will be false.  This formulation only checks for whether or
-// not TargetFunc exist directly in the class being introspected.
-//
-// To get around this, we play a dirty trick with multiple inheritance.
-// First, We create a class BaseMixin that declares each function that we
-// want to probe for.  Then we create a class Base that inherits from both T
-// (the class we wish to probe) and BaseMixin.  Note that the function
-// signature in BaseMixin does not need to match the signature of the function
-// we are probing for; thus it's easiest to just use void(void).
-//
-// Now, if TargetFunc exists somewhere in T, then &Base::TargetFunc has an
-// ambiguous resolution between BaseMixin and T.  This lets us write the
-// following:
-//
-//   template <typename C>
-//   No GoodCheck(Helper<&C::TargetFunc>*);
-//
-//   template <typename C>
-//   Yes GoodCheck(...);
-//
-//   static const bool value = sizeof(GoodCheck<Base>(0)) == sizeof(Yes);
-//
-// Notice here that the variadic version of GoodCheck() returns Yes here
-// instead of No like the previous one. Also notice that we calculate |value|
-// by specializing GoodCheck() on Base instead of T.
-//
-// We've reversed the roles of the variadic, and Helper overloads.
-// GoodCheck(Helper<&C::TargetFunc>*), when C = Base, fails to be a valid
-// substitution if T::TargetFunc exists. Thus GoodCheck<Base>(0) will resolve
-// to the variadic version if T has TargetFunc.  If T::TargetFunc does not
-// exist, then &C::TargetFunc is not ambiguous, and the overload resolution
-// will prefer GoodCheck(Helper<&C::TargetFunc>*).
-//
-// This method of SFINAE will correctly probe for inherited names, but it cannot
-// typecheck those names.  It's still a good enough sanity check though.
-//
-// Works on gcc-4.2, gcc-4.4, and Visual Studio 2008.
-//
-// TODO(ajwong): Move to ref_counted.h or template_util.h when we've vetted
-// this works well.

-// -----------------------------------------------------------------------------
-// Introduction
-// -----------------------------------------------------------------------------
-//
-// The templated Callback class is a generalized function object. Together
-// with the Bind() function in bind.h, they provide a type-safe method for
-// performing partial application of functions.
-//
-// Partial application (or "currying") is the process of binding a subset of
-// a function's arguments to produce another function that takes fewer
-// arguments. This can be used to pass around a unit of delayed execution,
-// much like lexical closures are used in other languages. For example, it
-// is used in Chromium code to schedule tasks on different MessageLoops.
-//
-// A callback with no unbound input parameters (base::Callback<void(void)>)
-// is called a base::Closure. Note that this is NOT the same as what other
-// languages refer to as a closure -- it does not retain a reference to its
-// enclosing environment.
-//
-// MEMORY MANAGEMENT AND PASSING
-//
-// The Callback objects themselves should be passed by const-reference, and
-// stored by copy. They internally store their state via a refcounted class
-// and thus do not need to be deleted.
-//
-// The reason to pass via a const-reference is to avoid unnecessary
-// AddRef/Release pairs to the internal state.
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for basic stuff
-// -----------------------------------------------------------------------------
-//
-// BINDING A BARE FUNCTION
-//
-//   int Return5() { return 5; }
-//   base::Callback<int(void)> func_cb = base::Bind(&Return5);
-//   LOG(INFO) << func_cb.Run();  // Prints 5.
-//
-// BINDING A CLASS METHOD
-//
-//   The first argument to bind is the member function to call, the second is
-//   the object on which to call it.
-//
-//   class Ref : public base::RefCountedThreadSafe<Ref> {
-//    public:
-//     int Foo() { return 3; }
-//     void PrintBye() { LOG(INFO) << "bye."; }
-//   };
-//   scoped_refptr<Ref> ref = new Ref();
-//   base::Callback<void(void)> ref_cb = base::Bind(&Ref::Foo, ref);
-//   LOG(INFO) << ref_cb.Run();  // Prints out 3.
-//
-//   By default the object must support RefCounted or you will get a compiler
-//   error. If you're passing between threads, be sure it's
-//   RefCountedThreadSafe! See "Advanced binding of member functions" below if
-//   you don't want to use reference counting.
-//
-// RUNNING A CALLBACK
-//
-//   Callbacks can be run with their "Run" method, which has the same
-//   signature as the template argument to the callback.
-//
-//   void DoSomething(const base::Callback<void(int, std::string)>& callback) {
-//     callback.Run(5, "hello");
-//   }
-//
-//   Callbacks can be run more than once (they don't get deleted or marked when
-//   run). However, this precludes using base::Passed (see below).
-//
-//   void DoSomething(const base::Callback<double(double)>& callback) {
-//     double myresult = callback.Run(3.14159);
-//     myresult += callback.Run(2.71828);
-//   }
-//
-// PASSING UNBOUND INPUT PARAMETERS
-//
-//   Unbound parameters are specified at the time a callback is Run(). They are
-//   specified in the Callback template type:
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(int, const std::string&)> cb = base::Bind(&MyFunc);
-//   cb.Run(23, "hello, world");
-//
-// PASSING BOUND INPUT PARAMETERS
-//
-//   Bound parameters are specified when you create thee callback as arguments
-//   to Bind(). They will be passed to the function and the Run()ner of the
-//   callback doesn't see those values or even know that the function it's
-//   calling.
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(void)> cb = base::Bind(&MyFunc, 23, "hello world");
-//   cb.Run();
-//
-//   A callback with no unbound input parameters (base::Callback<void(void)>)
-//   is called a base::Closure. So we could have also written:
-//
-//   base::Closure cb = base::Bind(&MyFunc, 23, "hello world");
-//
-//   When calling member functions, bound parameters just go after the object
-//   pointer.
-//
-//   base::Closure cb = base::Bind(&MyClass::MyFunc, this, 23, "hello world");
-//
-// PARTIAL BINDING OF PARAMETERS
-//
-//   You can specify some parameters when you create the callback, and specify
-//   the rest when you execute the callback.
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(const std::string&)> cb = base::Bind(&MyFunc, 23);
-//   cb.Run("hello world");
-//
-//   When calling a function bound parameters are first, followed by unbound
-//   parameters.
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for advanced binding
-// -----------------------------------------------------------------------------
-//
-// BINDING A CLASS METHOD WITH WEAK POINTERS
-//
-//   base::Bind(&MyClass::Foo, GetWeakPtr());
-//
-//   The callback will not be run if the object has already been destroyed.
-//   DANGER: weak pointers are not threadsafe, so don't use this
-//   when passing between threads!
-//
-// BINDING A CLASS METHOD WITH MANUAL LIFETIME MANAGEMENT
-//
-//   base::Bind(&MyClass::Foo, base::Unretained(this));
-//
-//   This disables all lifetime management on the object. You're responsible
-//   for making sure the object is alive at the time of the call. You break it,
-//   you own it!
-//
-// BINDING A CLASS METHOD AND HAVING THE CALLBACK OWN THE CLASS
-//
-//   MyClass* myclass = new MyClass;
-//   base::Bind(&MyClass::Foo, base::Owned(myclass));
-//
-//   The object will be deleted when the callback is destroyed, even if it's
-//   not run (like if you post a task during shutdown). Potentially useful for
-//   "fire and forget" cases.
-//
-// IGNORING RETURN VALUES
-//
-//   Sometimes you want to call a function that returns a value in a callback
-//   that doesn't expect a return value.
-//
-//   int DoSomething(int arg) { cout << arg << endl; }
-//   base::Callback<void<int>) cb =
-//       base::Bind(base::IgnoreResult(&DoSomething));
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for binding parameters to Bind()
-// -----------------------------------------------------------------------------
-//
-// Bound parameters are specified as arguments to Bind() and are passed to the
-// function. A callback with no parameters or no unbound parameters is called a
-// Closure (base::Callback<void(void)> and base::Closure are the same thing).
-//
-// PASSING PARAMETERS OWNED BY THE CALLBACK
-//
-//   void Foo(int* arg) { cout << *arg << endl; }
-//   int* pn = new int(1);
-//   base::Closure foo_callback = base::Bind(&foo, base::Owned(pn));
-//
-//   The parameter will be deleted when the callback is destroyed, even if it's
-//   not run (like if you post a task during shutdown).
-//
-// PASSING PARAMETERS AS A scoped_ptr
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) {}
-//   scoped_ptr<Foo> f(new Foo);
-//   // f becomes null during the following call.
-//   base::Closure cb = base::Bind(&TakesOwnership, base::Passed(&f));
-//
-//   Ownership of the parameter will be with the callback until the it is run,
-//   when ownership is passed to the callback function. This means the callback
-//   can only be run once. If the callback is never run, it will delete the
-//   object when it's destroyed.
-//
-// PASSING PARAMETERS AS A scoped_refptr
-//
-//   void TakesOneRef(scoped_refptr<Foo> arg) {}
-//   scoped_refptr<Foo> f(new Foo)
-//   base::Closure cb = base::Bind(&TakesOneRef, f);
-//
-//   This should "just work." The closure will take a reference as long as it
-//   is alive, and another reference will be taken for the called function.
-//
-// PASSING PARAMETERS BY REFERENCE
-//
-//   Const references are *copied* unless ConstRef is used. Example:
-//
-//   void foo(const int& arg) { printf("%d %p\n", arg, &arg); }
-//   int n = 1;
-//   base::Closure has_copy = base::Bind(&foo, n);
-//   base::Closure has_ref = base::Bind(&foo, base::ConstRef(n));
-//   n = 2;
-//   foo(n);                        // Prints "2 0xaaaaaaaaaaaa"
-//   has_copy.Run();                // Prints "1 0xbbbbbbbbbbbb"
-//   has_ref.Run();                 // Prints "2 0xaaaaaaaaaaaa"
-//
-//   Normally parameters are copied in the closure. DANGER: ConstRef stores a
-//   const reference instead, referencing the original parameter. This means
-//   that you must ensure the object outlives the callback!
-//

-// Implementation notes
-// -----------------------------------------------------------------------------
-//
-// WHERE IS THIS DESIGN FROM:
-//
-// The design Callback and Bind is heavily influenced by C++'s
-// tr1::function/tr1::bind, and by the "Google Callback" system used inside
-// Google.
-//
-//
-// HOW THE IMPLEMENTATION WORKS:
-//
-// There are three main components to the system:
-//   1) The Callback classes.
-//   2) The Bind() functions.
-//   3) The arguments wrappers (e.g., Unretained() and ConstRef()).
-//
-// The Callback classes represent a generic function pointer. Internally,
-// it stores a refcounted piece of state that represents the target function
-// and all its bound parameters.  Each Callback specialization has a templated
-// constructor that takes an BindState<>*.  In the context of the constructor,
-// the static type of this BindState<> pointer uniquely identifies the
-// function it is representing, all its bound parameters, and a Run() method
-// that is capable of invoking the target.
-//
-// Callback's constructor takes the BindState<>* that has the full static type
-// and erases the target function type as well as the types of the bound
-// parameters.  It does this by storing a pointer to the specific Run()
-// function, and upcasting the state of BindState<>* to a
-// BindStateBase*. This is safe as long as this BindStateBase pointer
-// is only used with the stored Run() pointer.
-//
-// To BindState<> objects are created inside the Bind() functions.
-// These functions, along with a set of internal templates, are responsible for
-//
-//  - Unwrapping the function signature into return type, and parameters
-//  - Determining the number of parameters that are bound
-//  - Creating the BindState storing the bound parameters
-//  - Performing compile-time asserts to avoid error-prone behavior
-//  - Returning an Callback<> with an arity matching the number of unbound
-//    parameters and that knows the correct refcounting semantics for the
-//    target object if we are binding a method.
-//
-// The Bind functions do the above using type-inference, and template
-// specializations.
-//
-// By default Bind() will store copies of all bound parameters, and attempt
-// to refcount a target object if the function being bound is a class method.
-// These copies are created even if the function takes parameters as const
-// references. (Binding to non-const references is forbidden, see bind.h.)
-//
-// To change this behavior, we introduce a set of argument wrappers
-// (e.g., Unretained(), and ConstRef()).  These are simple container templates
-// that are passed by value, and wrap a pointer to argument.  See the
-// file-level comment in base/bind_helpers.h for more info.
-//
-// These types are passed to the Unwrap() functions, and the MaybeRefcount()
-// functions respectively to modify the behavior of Bind().  The Unwrap()
-// and MaybeRefcount() functions change behavior by doing partial
-// specialization based on whether or not a parameter is a wrapper type.
-//
-// ConstRef() is similar to tr1::cref.  Unretained() is specific to Chromium.
-//
-//
-// WHY NOT TR1 FUNCTION/BIND?
-//
-// Direct use of tr1::function and tr1::bind was considered, but ultimately
-// rejected because of the number of copy constructors invocations involved
-// in the binding of arguments during construction, and the forwarding of
-// arguments during invocation.  These copies will no longer be an issue in
-// C++0x because C++0x will support rvalue reference allowing for the compiler
-// to avoid these copies.  However, waiting for C++0x is not an option.
-//
-// Measured with valgrind on gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5), the
-// tr1::bind call itself will invoke a non-trivial copy constructor three times
-// for each bound parameter.  Also, each when passing a tr1::function, each
-// bound argument will be copied again.
-//
-// In addition to the copies taken at binding and invocation, copying a
-// tr1::function causes a copy to be made of all the bound parameters and
-// state.
-//
-// Furthermore, in Chromium, it is desirable for the Callback to take a
-// reference on a target object when representing a class method call.  This
-// is not supported by tr1.
-//
-// Lastly, tr1::function and tr1::bind has a more general and flexible API.
-// This includes things like argument reordering by use of
-// tr1::bind::placeholder, support for non-const reference parameters, and some
-// limited amount of subtyping of the tr1::function object (e.g.,
-// tr1::function<int(int)> is convertible to tr1::function<void(int)>).
-//
-// These are not features that are required in Chromium. Some of them, such as
-// allowing for reference parameters, and subtyping of functions, may actually
-// become a source of errors. Removing support for these features actually
-// allows for a simpler implementation, and a terser Currying API.
-//
-//
-// WHY NOT GOOGLE CALLBACKS?
-//
-// The Google callback system also does not support refcounting.  Furthermore,
-// its implementation has a number of strange edge cases with respect to type
-// conversion of its arguments.  In particular, the argument's constness must
-// at times match exactly the function signature, or the type-inference might
-// break.  Given the above, writing a custom solution was easier.
-//
-//
-// MISSING FUNCTIONALITY
-//  - Invoking the return of Bind.  Bind(&foo).Run() does not work;
-//  - Binding arrays to functions that take a non-const pointer.
-//    Example:
-//      void Foo(const char* ptr);
-//      void Bar(char* ptr);
-//      Bind(&Foo, "test");
-//      Bind(&Bar, "test");  // This fails because ptr is not const.

-//
-//   does not work, as gcc supports variable-length arrays whose sizes
-//   are determined at run-time (this is gcc's extension and not part
-//   of the C++ standard).  As a result, gcc fails to reject the
-//   following code with the simple definition:
-//
-//     int foo;
-//     COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
-//                               // not a compile-time constant.
-//
-// - By using the type CompileAssert<(bool(expr))>, we ensures that
-//   expr is a compile-time constant.  (Template arguments must be
-//   determined at compile-time.)
-//
-// - The outer parentheses in CompileAssert<(bool(expr))> are necessary
-//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
-//
-//     CompileAssert<bool(expr)>
-//
-//   instead, these compilers will refuse to compile
-//
-//     COMPILE_ASSERT(5 > 0, some_message);
-//
-//   (They seem to think the ">" in "5 > 0" marks the end of the
-//   template argument list.)
-//
-// - The array size is (bool(expr) ? 1 : -1), instead of simply
-//
-//     ((expr) ? 1 : -1).
-//
-//   This is to avoid running into a bug in MS VC 7.1, which

-
-// Macro with the boilerplate that makes a type move-only in C++03.
-//
-// USAGE
-//
-// This macro should be used instead of DISALLOW_COPY_AND_ASSIGN to create
-// a "move-only" type.  Unlike DISALLOW_COPY_AND_ASSIGN, this macro should be
-// the first line in a class declaration.
-//
-// A class using this macro must call .Pass() (or somehow be an r-value already)
-// before it can be:
-//
-//   * Passed as a function argument
-//   * Used as the right-hand side of an assignment
-//   * Returned from a function
-//
-// Each class will still need to define their own "move constructor" and "move
-// operator=" to make this useful.  Here's an example of the macro, the move
-// constructor, and the move operator= from the scoped_ptr class:
-//
-//  template <typename T>
-//  class scoped_ptr {
-//     MOVE_ONLY_TYPE_FOR_CPP_03(scoped_ptr, RValue)
-//   public:
-//    scoped_ptr(RValue& other) : ptr_(other.release()) { }
-//    scoped_ptr& operator=(RValue& other) {
-//      swap(other);
-//      return *this;
-//    }
-//  };
-//
-// Note that the constructor must NOT be marked explicit.
-//
-// For consistency, the second parameter to the macro should always be RValue
-// unless you have a strong reason to do otherwise.  It is only exposed as a
-// macro parameter so that the move constructor and move operator= don't look
-// like they're using a phantom type.
-//
-//
-// HOW THIS WORKS
-//
-// For a thorough explanation of this technique, see:
-//
-//   http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/Move_Constructor
-//
-// The summary is that we take advantage of 2 properties:
-//
-//   1) non-const references will not bind to r-values.
-//   2) C++ can apply one user-defined conversion when initializing a
-//      variable.
-//
-// The first lets us disable the copy constructor and assignment operator
-// by declaring private version of them with a non-const reference parameter.
-//
-// For l-values, direct initialization still fails like in
-// DISALLOW_COPY_AND_ASSIGN because the copy constructor and assignment
-// operators are private.
-//
-// For r-values, the situation is different. The copy constructor and
-// assignment operator are not viable due to (1), so we are trying to call
-// a non-existent constructor and non-existing operator= rather than a private
-// one.  Since we have not committed an error quite yet, we can provide an
-// alternate conversion sequence and a constructor.  We add
-//
-//   * a private struct named "RValue"
-//   * a user-defined conversion "operator RValue()"
-//   * a "move constructor" and "move operator=" that take the RValue& as
-//     their sole parameter.
-//
-// Only r-values will trigger this sequence and execute our "move constructor"
-// or "move operator=."  L-values will match the private copy constructor and
-// operator= first giving a "private in this context" error.  This combination
-// gives us a move-only type.
-//
-// For signaling a destructive transfer of data from an l-value, we provide a
-// method named Pass() which creates an r-value for the current instance
-// triggering the move constructor or move operator=.
-//
-// Other ways to get r-values is to use the result of an expression like a
-// function call.
-//
-// Here's an example with comments explaining what gets triggered where:
-//
-//    class Foo {
-//      MOVE_ONLY_TYPE_FOR_CPP_03(Foo, RValue);
-//
-//     public:
-//       ... API ...
-//       Foo(RValue other);           // Move constructor.
-//       Foo& operator=(RValue rhs);  // Move operator=
-//    };
-//
-//    Foo MakeFoo();  // Function that returns a Foo.
-//
-//    Foo f;
-//    Foo f_copy(f);  // ERROR: Foo(Foo&) is private in this context.
-//    Foo f_assign;
-//    f_assign = f;   // ERROR: operator=(Foo&) is private in this context.
-//
-//
-//    Foo f(MakeFoo());      // R-value so alternate conversion executed.
-//    Foo f_copy(f.Pass());  // R-value so alternate conversion executed.
-//    f = f_copy.Pass();     // R-value so alternate conversion executed.
-//
-//
-// IMPLEMENTATION SUBTLETIES WITH RValue
-//
-// The RValue struct is just a container for a pointer back to the original
-// object. It should only ever be created as a temporary, and no external
-// class should ever declare it or use it in a parameter.
-//
-// It is tempting to want to use the RValue type in function parameters, but
-// excluding the limited usage here for the move constructor and move
-// operator=, doing so would mean that the function could take both r-values
-// and l-values equially which is unexpected.  See COMPARED To Boost.Move for
-// more details.
-//
-// An alternate, and incorrect, implementation of the RValue class used by
-// Boost.Move makes RValue a fieldless child of the move-only type. RValue&
-// is then used in place of RValue in the various operators.  The RValue& is
-// "created" by doing *reinterpret_cast<RValue*>(this).  This has the appeal
-// of never creating a temporary RValue struct even with optimizations
-// disabled.  Also, by virtue of inheritance you can treat the RValue
-// reference as if it were the move-only type itself.  Unfortunately,
-// using the result of this reinterpret_cast<> is actually undefined behavior
-// due to C++98 5.2.10.7. In certain compilers (e.g., NaCl) the optimizer
-// will generate non-working code.
-//
-// In optimized builds, both implementations generate the same assembly so we
-// choose the one that adheres to the standard.
-//
-//
-// WHY HAVE typedef void MoveOnlyTypeForCPP03
-//
-// Callback<>/Bind() needs to understand movable-but-not-copyable semantics
-// to call .Pass() appropriately when it is expected to transfer the value.
-// The cryptic typedef MoveOnlyTypeForCPP03 is added to make this check
-// easy and automatic in helper templates for Callback<>/Bind().
-// See IsMoveOnlyType template and its usage in base/callback_internal.h
-// for more details.
-//
-//
-// COMPARED TO C++11
-//
-// In C++11, you would implement this functionality using an r-value reference
-// and our .Pass() method would be replaced with a call to std::move().
-//
-// This emulation also has a deficiency where it uses up the single
-// user-defined conversion allowed by C++ during initialization.  This can
-// cause problems in some API edge cases.  For instance, in scoped_ptr, it is
-// impossible to make a function "void Foo(scoped_ptr<Parent> p)" accept a
-// value of type scoped_ptr<Child> even if you add a constructor to
-// scoped_ptr<> that would make it look like it should work.  C++11 does not
-// have this deficiency.
-//
-//
-// COMPARED TO Boost.Move
-//
-// Our implementation similar to Boost.Move, but we keep the RValue struct
-// private to the move-only type, and we don't use the reinterpret_cast<> hack.
-//
-// In Boost.Move, RValue is the boost::rv<> template.  This type can be used
-// when writing APIs like:
-//
-//   void MyFunc(boost::rv<Foo>& f)
-//
-// that can take advantage of rv<> to avoid extra copies of a type.  However you
-// would still be able to call this version of MyFunc with an l-value:
-//
-//   Foo f;
-//   MyFunc(f);  // Uh oh, we probably just destroyed |f| w/o calling Pass().
-//
-// unless someone is very careful to also declare a parallel override like:
-//
-//   void MyFunc(const Foo& f)
-//
-// that would catch the l-values first.  This was declared unsafe in C++11 and
-// a C++11 compiler will explicitly fail MyFunc(f).  Unfortunately, we cannot
-// ensure this in C++03.
-//
-// Since we have no need for writing such APIs yet, our implementation keeps
-// RValue private and uses a .Pass() method to do the conversion instead of
-// trying to write a version of "std::move()." Writing an API like std::move()
-// would require the RValue struct to be public.
-//
-//
-// CAVEATS
-//
-// If you include a move-only type as a field inside a class that does not
-// explicitly declare a copy constructor, the containing class's implicit
-// copy constructor will change from Containing(const Containing&) to
-// Containing(Containing&).  This can cause some unexpected errors.
-//
-//   http://llvm.org/bugs/show_bug.cgi?id=11528
-//
-// The workaround is to explicitly declare your copy constructor.

-// Scopers help you manage ownership of a pointer, helping you easily manage a
-// pointer within a scope, and automatically destroying the pointer at the end
-// of a scope.  There are two main classes you will use, which correspond to the
-// operators new/delete and new[]/delete[].
-//
-// Example usage (scoped_ptr<T>):
-//   {
-//     scoped_ptr<Foo> foo(new Foo("wee"));
-//   }  // foo goes out of scope, releasing the pointer with it.
-//
-//   {
-//     scoped_ptr<Foo> foo;          // No pointer managed.
-//     foo.reset(new Foo("wee"));    // Now a pointer is managed.
-//     foo.reset(new Foo("wee2"));   // Foo("wee") was destroyed.
-//     foo.reset(new Foo("wee3"));   // Foo("wee2") was destroyed.
-//     foo->Method();                // Foo::Method() called.
-//     foo.get()->Method();          // Foo::Method() called.
-//     SomeFunc(foo.release());      // SomeFunc takes ownership, foo no longer
-//                                   // manages a pointer.
-//     foo.reset(new Foo("wee4"));   // foo manages a pointer again.
-//     foo.reset();                  // Foo("wee4") destroyed, foo no longer
-//                                   // manages a pointer.
-//   }  // foo wasn't managing a pointer, so nothing was destroyed.
-//
-// Example usage (scoped_ptr<T[]>):
-//   {
-//     scoped_ptr<Foo[]> foo(new Foo[100]);
-//     foo.get()->Method();  // Foo::Method on the 0th element.
-//     foo[10].Method();     // Foo::Method on the 10th element.
-//   }
-//
-// These scopers also implement part of the functionality of C++11 unique_ptr
-// in that they are "movable but not copyable."  You can use the scopers in
-// the parameter and return types of functions to signify ownership transfer
-// in to and out of a function.  When calling a function that has a scoper
-// as the argument type, it must be called with the result of an analogous
-// scoper's Pass() function or another function that generates a temporary;
-// passing by copy will NOT work.  Here is an example using scoped_ptr:
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) {
-//     // Do something with arg
-//   }
-//   scoped_ptr<Foo> CreateFoo() {
-//     // No need for calling Pass() because we are constructing a temporary
-//     // for the return value.
-//     return scoped_ptr<Foo>(new Foo("new"));
-//   }
-//   scoped_ptr<Foo> PassThru(scoped_ptr<Foo> arg) {
-//     return arg.Pass();
-//   }
-//
-//   {
-//     scoped_ptr<Foo> ptr(new Foo("yay"));  // ptr manages Foo("yay").
-//     TakesOwnership(ptr.Pass());           // ptr no longer owns Foo("yay").
-//     scoped_ptr<Foo> ptr2 = CreateFoo();   // ptr2 owns the return Foo.
-//     scoped_ptr<Foo> ptr3 =                // ptr3 now owns what was in ptr2.
-//         PassThru(ptr2.Pass());            // ptr2 is correspondingly NULL.
-//   }
-//
-// Notice that if you do not call Pass() when returning from PassThru(), or
-// when invoking TakesOwnership(), the code will not compile because scopers
-// are not copyable; they only implement move semantics which require calling
-// the Pass() function to signify a destructive transfer of state. CreateFoo()
-// is different though because we are constructing a temporary on the return
-// line and thus can avoid needing to call Pass().
-//
-// Pass() properly handles upcast in initialization, i.e. you can use a
-// scoped_ptr<Child> to initialize a scoped_ptr<Parent>:
-//
-//   scoped_ptr<Foo> foo(new Foo());
-//   scoped_ptr<FooParent> parent(foo.Pass());
-//
-// PassAs<>() should be used to upcast return value in return statement:
-//
-//   scoped_ptr<Foo> CreateFoo() {
-//     scoped_ptr<FooChild> result(new FooChild());
-//     return result.PassAs<Foo>();
-//   }
-//
-// Note that PassAs<>() is implemented only for scoped_ptr<T>, but not for
-// scoped_ptr<T[]>. This is because casting array pointers may not be safe.

+//     friend class RefCounted<MyFoo>;  // Allow destruction by RefCounted<>.

+//       foo->Method(param);
+//   }
+//
+// The above examples show how scoped_refptr<T> acts like a pointer to T.
+// Given two scoped_refptr<T> classes, it is also possible to exchange
+// references between the two objects, like so:
+//
+//   {
+//     scoped_refptr<MyFoo> a = MakeRefCounted<MyFoo>();
+//     scoped_refptr<MyFoo> b;
+//
+//     b.swap(a);
+//     // now, |b| references the MyFoo object, and |a| references nullptr.
+//   }
+//
+// To make both |a| and |b| in the above example reference the same MyFoo
+// object, simply use the assignment operator:
+//
+//   {
+//     scoped_refptr<MyFoo> a = MakeRefCounted<MyFoo>();
+//     scoped_refptr<MyFoo> b;
+//
+//     b = a;
+//     // now, |a| and |b| each own a reference to the same MyFoo object.
+//   }
+//
+// Also see Chromium's ownership and calling conventions:
+// https://chromium.googlesource.com/chromium/src/+/lkgr/styleguide/c++/c++.md#object-ownership-and-calling-conventions
+// Specifically:
+//   If the function (at least sometimes) takes a ref on a refcounted object,
+//   declare the param as scoped_refptr<T>. The caller can decide whether it
+//   wishes to transfer ownership (by calling std::move(t) when passing t) or
+//   retain its ref (by simply passing t directly).
+//   In other words, use scoped_refptr like you would a std::unique_ptr except
+//   in the odd case where it's required to hold on to a ref while handing one

+// ScopedTypeRef<> is patterned after std::unique_ptr<>, but maintains ownership
+// of a reference to any type that is maintained by Retain and Release methods.
+//
+// The Traits structure must provide the Retain and Release methods for type T.
+// A default ScopedTypeRefTraits is used but not defined, and should be defined
+// for each type to use this interface. For example, an appropriate definition
+// of ScopedTypeRefTraits for CGLContextObj would be:
+//
+//   template<>
+//   struct ScopedTypeRefTraits<CGLContextObj> {
+//     static CGLContextObj InvalidValue() { return nullptr; }

+//     static void Release(CGLContextObj object) { CGLContextRelease(object); }
+//   };
+//
+// For the many types that have pass-by-pointer create functions, the function
+// InitializeInto() is provided to allow direct initialization and assumption
+// of ownership of the object. For example, continuing to use the above
+// CGLContextObj specialization:
+//
+//   base::ScopedTypeRef<CGLContextObj> context;
+//   CGLCreateContext(pixel_format, share_group, context.InitializeInto());
+//
+// For initialization with an existing object, the caller may specify whether
+// the ScopedTypeRef<> being initialized is assuming the caller's existing
+// ownership of the object (and should not call Retain in initialization) or if
+// it should not assume this ownership and must create its own (by calling
+// Retain in initialization). This behavior is based on the |policy| parameter,
+// with |ASSUME| for the former and |RETAIN| for the latter. The default policy

-// WHAT:
-// A version of std::basic_string that provides 2-byte characters even when
-// wchar_t is not implemented as a 2-byte type. You can access this class as
-// string16. We also define char16, which string16 is based upon.
-//
-// WHY:
-// On Windows, wchar_t is 2 bytes, and it can conveniently handle UTF-16/UCS-2
-// data. Plenty of existing code operates on strings encoded as UTF-16.
-//
-// On many other platforms, sizeof(wchar_t) is 4 bytes by default. We can make
-// it 2 bytes by using the GCC flag -fshort-wchar. But then std::wstring fails
-// at run time, because it calls some functions (like wcslen) that come from
-// the system's native C library -- which was built with a 4-byte wchar_t!
-// It's wasteful to use 4-byte wchar_t strings to carry UTF-16 data, and it's
-// entirely improper on those systems where the encoding of wchar_t is defined
-// as UTF-32.
-//
-// Here, we define string16, which is similar to std::wstring but replaces all
-// libc functions with custom, 2-byte-char compatible routines. It is capable
-// of carrying UTF-16-encoded data.

-// std::basic_string<> in GNU libstdc++ contains a static data member,
-// _S_empty_rep_storage, to represent empty strings.  When an operation such
-// as assignment or destruction is performed on a string, causing its existing
-// data member to be invalidated, it must not be freed if this static data
-// member is being used.  Otherwise, it counts as an attempt to free static
-// (and not allocated) data, which is a memory error.
-//
-// Generally, due to C++ template magic, _S_empty_rep_storage will be marked
-// as a coalesced symbol, meaning that the linker will combine multiple
-// instances into a single one when generating output.
-//
-// If a string class is used by multiple shared libraries, a problem occurs.
-// Each library will get its own copy of _S_empty_rep_storage.  When strings
-// are passed across a library boundary for alteration or destruction, memory
-// errors will result.  GNU libstdc++ contains a configuration option,
-// --enable-fully-dynamic-string (_GLIBCXX_FULLY_DYNAMIC_STRING), which
-// disables the static data member optimization, but it's a good optimization
-// and non-STL code is generally at the mercy of the system's STL
-// configuration.  Fully-dynamic strings are not the default for GNU libstdc++
-// libstdc++ itself or for the libstdc++ installations on the systems we care
-// about, such as Mac OS X and relevant flavors of Linux.
-//
-// See also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24196 .
-//
-// To avoid problems, string classes need to be explicitly instantiated only
-// once, in exactly one library.  All other string users see it via an "extern"
-// declaration.  This is precisely how GNU libstdc++ handles
-// std::basic_string<char> (string) and std::basic_string<wchar_t> (wstring).
-//
-// This also works around a Mac OS X linker bug in ld64-85.2.1 (Xcode 3.1.2),
-// in which the linker does not fully coalesce symbols when dead code
-// stripping is enabled.  This bug causes the memory errors described above
-// to occur even when a std::basic_string<> does not cross shared library
-// boundaries, such as in statically-linked executables.
-//
-// TODO(mark): File this bug with Apple and update this note with a bug number.

+// If "ProductName" and/or "ProductVersion" are set then the specified values
+// will be included in the crash dump metadata. On macOS if these values are set
+// to NULL then they will be retrieved from the Info.plist file using the
+// "CFBundleName" and "CFBundleShortVersionString" keys respectively.
+//
+// If "AppName" is set on Windows then crash report information (metrics,
+// database and dumps) will be stored locally on disk under the
+// "C:\Users\[CurrentUser]\AppData\Local\[AppName]\User Data" folder. On other
+// platforms the CefSettings.user_data_path value will be used.
+//
+// If "ExternalHandler" is set on Windows then the specified exe will be
+// launched as the crashpad-handler instead of re-launching the main process
+// exe. The value can be an absolute path or a path relative to the main exe
+// directory. On Linux the CefSettings.browser_subprocess_path value will be
+// used. On macOS the existing subprocess app bundle will be used.
+//
+// If "BrowserCrashForwardingEnabled" is set to true (1) on macOS then browser
+// process crashes will be forwarded to the system crash reporter. This results
+// in the crash UI dialog being displayed to the user and crash reports being
+// logged under "~/Library/Logs/DiagnosticReports". Forwarding of crash reports
+// from non-browser processes and Debug builds is always disabled.
+//
+// If "ServerURL" is set then crashes will be uploaded as a multi-part POST
+// request to the specified URL. Otherwise, reports will only be stored locally
+// on disk.
+//
+// If "RateLimitEnabled" is set to true (1) then crash report uploads will be
+// rate limited as follows:
+//  1. If "MaxUploadsPerDay" is set to a positive value then at most the
+//     specified number of crashes will be uploaded in each 24 hour period.
+//  2. If crash upload fails due to a network or server error then an
+//     incremental backoff delay up to a maximum of 24 hours will be applied for
+//     retries.
+//  3. If a backoff delay is applied and "MaxUploadsPerDay" is > 1 then the
+//     "MaxUploadsPerDay" value will be reduced to 1 until the client is
+//     restarted. This helps to avoid an upload flood when the network or
+//     server error is resolved.
+// Rate limiting is not supported on Linux.
+//
+// If "MaxDatabaseSizeInMb" is set to a positive value then crash report storage
+// on disk will be limited to that size in megabytes. For example, on Windows
+// each dump is about 600KB so a "MaxDatabaseSizeInMb" value of 20 equates to
+// about 34 crash reports stored on disk. Not supported on Linux.
+//
+// If "MaxDatabaseAgeInDays" is set to a positive value then crash reports older
+// than the specified age in days will be deleted. Not supported on Linux.

+// Implement this structure to handle events related to cef_frame_t life span.
+// The order of callbacks is:
+//
+// (1) During initial cef_browser_host_t creation and navigation of the main
+// frame: - cef_frame_handler_t::OnFrameCreated => The initial main frame object
+// has been
+//   created. Any commands will be queued until the frame is attached.
+// - cef_frame_handler_t::OnMainFrameChanged => The initial main frame object
+// has
+//   been assigned to the browser.
+// - cef_life_span_handler_t::OnAfterCreated => The browser is now valid and can
+// be
+//   used.
+// - cef_frame_handler_t::OnFrameAttached => The initial main frame object is
+// now
+//   connected to its peer in the renderer process. Commands can be routed.
+//
+// (2) During further cef_browser_host_t navigation/loading of the main frame
+// and/or sub-frames: - cef_frame_handler_t::OnFrameCreated => A new main frame
+// or sub-frame object has
+//   been created. Any commands will be queued until the frame is attached.
+// - cef_frame_handler_t::OnFrameAttached => A new main frame or sub-frame
+// object is
+//   now connected to its peer in the renderer process. Commands can be routed.
+// - cef_frame_handler_t::OnFrameDetached => An existing main frame or sub-frame
+//   object has lost its connection to the renderer process. If multiple objects
+//   are detached at the same time then notifications will be sent for any
+//   sub-frame objects before the main frame object. Commands can no longer be
+//   routed and will be discarded.
+// - cef_frame_handler_t::OnMainFrameChanged => A new main frame object has been
+//   assigned to the browser. This will only occur with cross-origin navigation
+//   or re-navigation after renderer process termination (due to crashes, etc).
+//
+// (3) During final cef_browser_host_t destruction of the main frame: -
+// cef_frame_handler_t::OnFrameDetached => Any sub-frame objects have lost their
+//   connection to the renderer process. Commands can no longer be routed and
+//   will be discarded.
+// - cef_life_span_handler_t::OnBeforeClose => The browser has been destroyed. -
+// cef_frame_handler_t::OnFrameDetached => The main frame object have lost its
+//   connection to the renderer process. Notifications will be sent for any
+//   sub-frame objects before the main frame object. Commands can no longer be
+//   routed and will be discarded.
+// - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
+// been
+//   removed from the browser.
+//
+// Cross-origin navigation and/or loading receives special handling.
+//
+// When the main frame navigates to a different origin the OnMainFrameChanged
+// callback (2) will be executed with the old and new main frame objects.
+//
+// When a new sub-frame is loaded in, or an existing sub-frame is navigated to,
+// a different origin from the parent frame, a temporary sub-frame object will
+// first be created in the parent's renderer process. That temporary sub-frame
+// will then be discarded after the real cross-origin sub-frame is created in
+// the new/target renderer process. The client will receive cross-origin
+// navigation callbacks (2) for the transition from the temporary sub-frame to
+// the real sub-frame. The temporary sub-frame will not recieve or execute
+// commands during this transitional period (any sent commands will be
+// discarded).
+//
+// When a new popup browser is created in a different origin from the parent
+// browser, a temporary main frame object for the popup will first be created in
+// the parent's renderer process. That temporary main frame will then be
+// discarded after the real cross-origin main frame is created in the new/target
+// renderer process. The client will recieve creation and initial navigation
+// callbacks (1) for the temporary main frame, followed by cross-origin
+// navigation callbacks (2) for the transition from the temporary main frame to
+// the real main frame. The temporary main frame may receive and execute
+// commands during this transitional period (any sent commands may be executed,
+// but the behavior is potentially undesirable since they execute in the parent
+// browser's renderer process and not the new/target renderer process).
+//
+// Callbacks will not be executed for placeholders that may be created during
+// pre-commit navigation for sub-frames that do not yet exist in the renderer
+// process. Placeholders will have cef_frame_t::get_identifier() == -4.
