2004-03-07 Sven Neumann <sven@gimp.org> Made size of undo previews configurable. Not dynamic for now, but at least not hardcoded any longer. Fixes bug #119905: * app/config/gimpcoreconfig.[ch] * app/config/gimprc-blurbs.h: added "undo-preview-size" property. * app/core/gimpundo.[ch]: use the new property instead of a hardcoded value. * app/widgets/gimpundoeditor.[ch]: added a "preview-size" construct property. * app/gui/dialogs-constructors.c: changed accordingly. * app/gui/preferences-dialog.c: added a widget to control the undo preview size.
