    Fixed <rdar://problem/3882212> REGRESSION: Images clipped instead of scaled
        Fixed <rdar://problem/3884088> Crash terminating image load

        Also added code to turn off color correction for images created
        via CGImageSources.  This code is currently disabled because CG
        can't change the color space of images loaded progressively.
        Further, according to Dave Hayward, CG will no longer attempt
        to color correct images that don't have embedded profiles as of
        Tiger 8A306.
