What about defining this class inside of AutoclickController, such that it is
externally accessible as

  AutoclickController::Delegate

gesture should be capitalized to Gesture, so AutoclickGestureDelegate. Then
rename the file to autoclick_gesture_delegate.h

+ public:
+  virtual ~AutoclickgestureDelegate() {}
+
+  // The actual task of starting the display of  a gesture.

How about comments like:

  Called when an autoclick gesture begins.

  Called when the autoclick gesture has ended, either because the mouse moved or
because the autoclick completed.

The delegate doesn't have to be related to the display of the gesture; for
example, it could be used in a test.

Done.

[sammiequon, 2016/06/07 18:06:16]

Done.

+  virtual void StartGesture(int delay_ms, gfx::Point center) = 0;
+
+  // The actual task of stopping a gesture from being displayed.
+  virtual void StopGesture() = 0;
+
+  virtual void SetGestureCenter(gfx::Point center) = 0;

Add DISALLOW_COPY_AND_ASSIGN(AutoclickgestureDelegate) to the end of this class.

[jdufault, 2016/06/03 22:02:44]

Please add a comment to SetGestureCenter.
