Author: Vittorio Giovara <[email protected]> Committer: Vittorio Giovara <[email protected]> Date: Fri Feb 27 19:00:25 2015 +0000 aic: Fix decoding files with odd dimensions Normally the aic decoder finds the proper slice combination (multiple of some number less than 32) but in case of odd width, it resorts to the default values, which were actually swapped. The number of slices is modified to account for such odd width cases.
