Use the more efficient translate operation when possible during mosaic build
----------------------------------------------------------------------------
Key: GEOT-2779
URL: http://jira.codehaus.org/browse/GEOT-2779
Project: GeoTools
Issue Type: Improvement
Components: gc imagemosaic
Reporter: Andrea Aime
Assignee: Daniele Romagnoli
Fix For: 2.6-RC1
Attachments: mosaicTranslate.patch
The attached patch make the mosaic use the translate operation instead of the
affine one when the operation is a mere translation. The speed-up factor is
significant, 25% on some tests I'm running that are also disk i/o bound
(coverages much bigger than the memory available).
