2008-08-28 Martin Nordholts <martinn@svn.gnome.org> * app/core/gimpimage.[ch]: Make the size-changed-detailed signal also contain previous image size. * app/display/gimpdisplayshell-handlers.c (gimp_display_shell_size_changed_detailed_handler): Take the previous image size into account and center the image if it starts to fit (axis indepentently) in the viewport due to the resize. * app/core/gimpundo.h * app/core/gimpimage-undo.c * app/core/gimpimageundo.[ch] * app/core/gimpimage-undo-push.[ch]: Manage the previous-size-information. * app/core/gimpimage-crop.c * app/core/gimpimage-scale.c * app/core/gimpimage-rotate.c * app/core/gimpimage-resize.c: Propagate previous size to the size-changed-detailed signal emission and the undo-system. svn path=/trunk/; revision=26804
