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.

8ed155dcc1 Fix raw_decode test so it works on big-endian machines. 
The test case was ignoring the documented API for TIFFReadRGBATile,
namely that the output pixels are uint32's and the macros TIFFGetR etc
should be used to fetch the pixel components.

Original patch by Marcus Meissner, somewhat cleaned up by me.
