* NEW: Update copyright year to 2013. [GB.FORM] * NEW: ImageView is a new control that allows to view an image inside a scrolled view, at different zoom levels. * BUG: FileProperties now works correctly if 'gb.desktop' is not used. * NEW: The FileProperties preview tab now uses an ImageView control and has a toolbar to zoom the preview. * BUG: Add the 'linux' and 'gnu' icon in the stock icon list. git-svn-id: svn://localhost/gambas/trunk@5770 867c0c6c-44f3-4631-809d-bfa615b0a4ec
