We still consume huge memory while converting comparefiles/dina3_watermark.pdf into PDF/A or PDF/X or with CompatibilityLevel=1.3 or with ps2write. Since now I've got some experience with clist, I would like to assist Ken with implementing a banding while converting modern PDF objects into older vector formats that don't allow to include them as high level objects. Particularly we need to do a banding while converting a transparency into bitmaps.
