Here's a patch to correct an issue with creating G4-compressed PDFs.

The issue is caused by == being used to compare bitfields when only
one bit is intended to be compared. Some of the tiffs I have had both
T2P_CS_ICCBASED and T2P_CS_BILEVEL set; therefore, the current code
will fail, producing certain pages that are inverted.

The patch follows, and is also attached.
