// A simple thread abstraction that establishes a message loop on a new thread.
// The consumer uses cef_task_runner_t to execute code on the thread's message
// loop. The thread is terminated when the cef_thread_t object is destroyed or
// stop() is called. All pending tasks queued on the thread's message loop will
// run to completion before the thread is terminated. cef_thread_create() can be
// called on any valid CEF thread in either the browser or render process. This
// structure should only be used for tasks that require a dedicated thread. In
// most cases you can post tasks to an existing CEF thread instead of creating a
// new one; see cef_task.h for details.
