-// with multiple frames (e.g. ico files), a frame with a size as close as
-// possible to |desired_image_frame_size| is chosen (tries to take one in larger
-// size if there's no precise match). Passing gfx::Size() as
-// |desired_image_frame_size| is also supported and will result in chosing the
-// smallest available size.
-// Upon completion, |callback| is invoked on the calling thread TaskRunner with
-// an SkBitmap argument. The SkBitmap will be null on failure and non-null on
-// success.
