* [antonin] changed remaining "WIN32" to "_WIN32"
! [antonin] libopenjpeg has no more dependency on LCMS lib. Everything concerning color (icc profile, conversion to rgb, etc) has been put outside libopenjpeg and is used in j2k_to_image.c and mj2_to_frames.c.
- [antonin] removed "opj_convert{.c,.h}"
+ [antonin] added a directory "common/" that contains "getopt{.c,.h}" (previously in "codec/compat").
+ [antonin] added files "color{.c,.h}" in "common/" that define the code for icc profile management and sycc_to_rgb conversion
+ [antonin] added "common/format_defs.h" that contains common definitions used in image_to_j2k, j2k_to_image, j2k_dump.

010ae27471
Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.

Fixed a bug in JPWL module, which prevented to exploit the full error correction capability of RS codes (e.g. it gave up at 5 errors, even if 6 were correctable); defined a JPWL_MAXIMUM_EPB_ROOM for better customization of the maximum dimension of EPBs (the dimension is pre-calculated on an hypothesis, if it goes beyond 65535 there will be problems, thus we give a little less than the max, let's say 65450)
