      On retina displays, the image returned by TestCase.grabImage() should be twice the size of the image returned on non-retina displays, as every logical pixel is represented by two physical pixels. It is, however, cropped to the size of the window, so pixels exceeding the window size cannot be accessed, although they are visible.

      See the attached test to reproduce the problem.
