Support for Cancel in PictureController

The PictureController saves the state of a picture when you begin to edit. If you decide to cancel editing, the picture reverts to the original, so if the user has changed the frame during editing, we need to revert the frame too. Let's make these changes now:

File: PictureController.cs

Add a variable for the startFrame to the top of the class:

    private GameObject startFrame; 

Add this to SavePictureProperties:

        startFrame = Instantiate(GetCurrentFrame()); 
        startFrame.SetActive(false); 
 

Then use it in RestorePictureProperties, which is called by CancelEdit:

        startFrame.SetActive(true); 
        SetFrame(startFrame); 

Note that we've instantiated a new game object, and it should be cleaned up when we exit editing ...
