As discussed, let's pass scoped_ptr<CaptureScreenshotResponse> here, which would
have set_xxxx and SendXXXResponse methods, and would store the command inside.
Method could return void then.

+  Response CanEmulate(bool* result);
+
+  Response StartScreencast(const std::string* format,
+                           const int* quality,

+                           const int* max_height);
+
+  Response StopScreencast();
+  Response HandleJavaScriptDialog(bool accept, const std::string* prompt_text);
+
+  scoped_refptr<DevToolsProtocol::Response> QueryUsageAndQuota(
+      const std::string& security_origin,
