gwt.g2d.client.graphics.ImageData
ImageData wrapper around the GWT ImageData, so that it can work with Color instead of the incredibly inwieldy getRedAt etc functions. @author Karel

    while (it.hasPrevious()) {
      Long id = it.previous();
      Surface surface = fIdToSurface.get(id);
      
      // get the color at the given location
      ImageData data = surface.getImageData(x, y, 1, 1);
      double alpha = data.getAlpha(0, 0);
      
      // hit is not transparent - we got a hit!
      if (alpha > Double.MIN_VALUE) {
        
        // look up color
