Clean up some warnings from MSVC. Thanks to Russell Lang for the report.

Fix image compositor. Code is not beautiful, but works.

As per raph's suggestion, switch to byte-wise addressing for the image data. It solves some endianness problems, and saves a significant amount of memory since page and pattern dictionaries contain many small (< 32 pixels wide) images.

Oops. Previous stride calculation was correct. Also remove obsolete png test code.

We've been using (and want) the image stride in bytes, not words.

#ifdef the debug fprintf()s. comment cleanup. actually transpose on TRANSPOSED.

Text region decoding now seems to decode 042_10.jb2 correctly. Added IAID decoding procedure. Changed jbig2_decode_text_region to use IAID procedure. Fixed off-by-one errors in corner alignment calculations. Added for (;;) loop for 3c, corresponding to looping over all symbol instances in a strip (outer while loop corresponds to looping over all strips in the region). Fixed predicates in CURS updating logic.

another checkpoint of text region decoding work. referred-to segment info is correct now.

Gratuitous renaming. Promote the segment header to Jbig2Segment and use it to store intermediate results rather than the results objects raph had sketched.
Ralph Giles

Treat seg_idx=-1 specially in the error callback, since we're using that for cases where the segment number is inappropriate or not available.

Generic regions decode into Jbig2Image structures, which are then (trivially) composited with the page buffer as the final step in handling the segment. We now write the page data out at out.png or out.pbm. Compile with -DOUTPUT_PBM for the old behavior.

Beginnings of text segment handling. Parse (most of) the text region segment header. Move the region segment info parser to jbig2_segment.c and jbig2_priv.h since this is shared by all region segment types.

Fix a precedence bug which prevented using the first page structure.
