Don't we need a delay here, and a delay PointerActionType?

+  int index;
+  gfx::PointF position;
+  PointerActionType pointer_action_type;
+  bool process;

What's this |process| bool for?

+
+  static const SyntheticPointerActionParams* Cast(
+      const SyntheticGestureParams* gesture_params);
+};
+
+}  // namespace content

+#endif  // CONTENT_COMMON_INPUT_SYNTHETIC_POINTER_ACTION_PARAMS_H_
