I would probably update this a bit more since threading doesn't matter.  We
should consider what this class is responsible for now that it isn't the bridge
between the two threads.  Can you update the comment?

Maybe something like "This class stores UI position data that will be used when
rendering the remote desktop"?

     /** Stores pan and zoom configuration and converts image coordinates to screen coordinates. */
     public Matrix transform = new Matrix();
 
     public int screenWidth = 0;
     public int screenHeight = 0;
     public int imageWidth = 0;
     public int imageHeight = 0;
