Bug: Wrong resolution level size arithmetic

Reported by: cxallan Owned by: cxallan
Priority: minor Milestone: OMERO-Beta4.3
Component: Bio-Formats Version: n.a.
Keywords: n.a. Cc: jburel, mlinkert

Description

In cases where the tile size is not a power of two, rounding error can occur at low resolution levels resulting in incorrect tile sizes being calculated vs. the JPEG 2000 specification. In the JPEG 2000 specification, decomposition levels are calculated using a "round up" algorithm.
