This problem was caused by the fix for 5039494.
Starting this fix, the ImageReader.computeRegion() procedure is used to compute the destination region. In order to avoid discrepancy between calculated destination region and destination offset from the param, we should also update the destinationOffset according to calculated values.
This was a regression introduced in mustang-b03. Specifically, the test
started failing with the 2004-05-06.mustang 2D nightly build. The only
relevant change in that build was a fix for 5039494; based on the diffs,
it looks like that fix caused this test failure. We should find a fix for
this soon, since it has been a constant source of failure for our
nightly regression test runs.
