Wrong encoding of small tiles with high level number

[gcode-importer]

Originally reported on Google Code with ID 239

What steps will reproduce the problem?
1. Take a large image (say 3840x2160) and define the tile size a bit smaller to make
one large tile and three smaller (say -t 3810,2130) and opj_compress with -n 6 or higher.
2. When DWT division comes to input width=1 (OPJ_INT32 rw in dwt.c, line 390) or  the
output for the tile is visibly incorrect.
3. There is a similar problem when tile height comes to 1 and then there is another
DWT level so it repeats the computation with height 1 (it should break in that case).


What is the expected output? What do you see instead?
The output j2k image is visibly malformed on the small tiles. 

What version of the product are you using? On what operating system?
r2345, Ubuntu Linux, 3.2.0-48-generic, x86_64

Seems like I can reproduce it over here:

$ ./bin/opj_compress -i ../../data/input/nonregression/ElephantDream_4K.tif -o issue239.jp2
-n 7 -t 4046,2130
