Add knownfailures-Ubuntu12.04-gcc4.6.3-x86_64-Release-3rdP.txt
...
For some reason, the OPJ_CI_ARCH=x86_64 OPJ_CI_BUILD_CONFIGURATION=Release OPJ_NUM_THREADS=2
configuration fails once PR1010 has been merged in master
( https://travis-ci.org/uclouvain/openjpeg/jobs/272219011 ) whereas (almost) the same
code in my branch didn't fail per https://travis-ci.org/rouault/openjpeg/jobs/271738113
The errors we get are the same as with the other x86_64 compilers, so nothing alarming here.

Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images
...
* Only works for single-tiled images --> will error out cleanly, as currently
in other cases
* Save re-reading the codestream for the tile, and re-use code-blocks of the
previous decoding pass.
* Future improvements might involve improving opj_decompress, and the image writing logic,
to use this strategy.

Various changes to allow tile buffers of more than 4giga pixels

Untested though, since that means a tile buffer of at least 16 GB. So
there might be places where uint32 overflow on multiplication still occur...

However the intermediate buffer for decoding must still be smaller than 4
billion pixels, so this is useful for decoding at a lower resolution level,
or subtile decoding.

Sub-tile decoding: only allocate tile component buffer of the needed dimension
...
Instead of being the full tile size.
* Use a sparse array mechanism to store code-blocks and intermediate stages of
IDWT.
* IDWT, DC level shift and MCT stages are done just on that smaller array.
* Improve copy of tile component array to final image, by saving an intermediate
buffer.
* For full-tile decoding at reduced resolution, only allocate the tile buffer to
the reduced size, instead of the full-resolution size.

Make opj_set_decode_area() and opj_decode() take into account opj_set_decoded_resolution_factor() ( #1006 , affect API use)
...
* Better document usage of opj_set_decode_area(), ie expecting coordinates
in full resolution/reference grid even if requesting at a lower resolution
factor
* Make sure that image->comps[].factor is set by opj_set_decode_area() and
opj_decode() from the value specified in opj_set_decoded_resolution_factor()
* opj_decompress: add 2 environmenet variables to test alternate ways of
using the API, namely USE_OPJ_SET_DECODED_RESOLUTION_FACTOR=YES to use
opj_set_decoded_resolution_factor() instead of parameters.cp_reduce, and
SKIP_OPJ_SET_DECODE_AREA=YES to not call opj_set_decode_area() if -d is
not specified.
