        The front graphic uses a layering technique to make the gradient transition at the lower corner of the image. In this particular circumstance we don't support the effect and apply a generic transparency to the whole shape. The shape is a white rectangle that should have had a gradient smask applied to it.

        The PostScript code that does the painting of the first gradient is in a BX ... EX block which defines an compatibility section. We can potentially ignore the commands in this block and if we do the PDF's main image renders correctly but without the gradient pattern in the lower corner.

        So the test worked a little better then expected, now no gradients are being drawn I guess BX..EX is more popular then I thought. Will gives this some more thought on how we are to apply the effect properly.
