The pdf interpreter needs to detect SMaskInData true in the file.  In this
case, hastransparency should be true and the pdf14 device pushed. The image
should be handled as a 3x type and the alpha channel will be interleaved with
the image data.  Jasper processes the file just fine, it is GS that is not
using the alpha channel properly nor paying attention to the SMaskInData
