EXIF problems and UI enhancements

I have some troubles with code handling EXIF infos. No problem with landscape orientation of photos but already rotated portrait photos have a curious artefact I can’t debug when saved with EXIF.

Thus, I continue with some UI enhancements which will result in faster launch of JGallery (associated with Java 5) : the different views will be better managed through a new class (Perspective & PerspectiveManager) and only created on demand. The perspective classes will also help coding such view behaviour, with less and clearer code bringing even more view features : Now views can be closed.
