Description

NITF driver fails on ​http://www.gwg.nga.mil/ntb/baseline/software/testfile/Nitfv2_1/i_3301c.ntf and ​http://www.gwg.nga.mil/ntb/baseline/software/testfile/Nitfv2_1/i_3301k.ntf

The attached patch changes the way that psImage->panBlockStart[iBlock] is computed to be more robust to different IMODE values when psImage->szIC == "NM". This fixes the problems on the two images.

I have confirmed the problem with i_3301k.ntf, but i_3301c.ntf seemed to be working fine as it was. I believe this patch can be summarized as fixing block offset computations for IC=NM, and IMODE=R data.

The patch (with a small adjustment to error reporting) committed in trunk as r12923. It is also likely suitable for 1.4 branch, but I lack the guts to apply it currently.
