Why !OS_CHROMEOS?
For platforms other than Mac, can we always set settings.begin_frame_receiver to
true in the Renderer?

+  settings.begin_frame_receiver = true;
+#elif defined(OS_MACOSX)
+  // Mac only uses browser compositor when delegated renderer is used.
+  if (cmd->HasSwitch(switches::kEnableDelegatedRenderer))
+    settings.begin_frame_receiver = true;
