Cropping can only be performed at the end of a pipeline

The following works:

augmentations = Rotate(10) |>
                Zoom((0.9, 1.1)) |>
                ScaleFixed((96, 96)) |>
                Maybe(FlipX()) |>
                CenterCrop((96, 96)) |>
                ImageToTensor()

but the following breaks (i.e. the images are not 96x96)

augmentations = Rotate(10) |>
                Zoom((0.9, 1.1)) |>
                ScaleFixed((96, 96)) |>
                CenterCrop((96, 96)) |>
                Maybe(FlipX()) |>
                ImageToTensor()

I don't know if this is a technical limitation (my fuzzy reading of the source code suggests yes), but if it is, then it should be properly documented.
