Fix (pdfwrite) : A fixed overflow in setup_image_compression.
DETAILS :
Bug 687164 "(pdfwrite) dina3_watermark.pdf generates a 293Meg PDF".
The bug persists since Sun Apr 30 01:26:41 2000 UTC.
EXPECTED DIFFERENCES :
The re-distilled dina3_watermark.pdf renders differently due to DCT compression applied.
