2007-11-15 Michael Natterer <mitch@gimp.org> * app/core/gimpviewable.[ch]: add read-only property "frozen" and new API gimp_viewable_preview_is_fozen(). Emit property notifications. * app/widgets/gimphistogramview.[ch]: add API to show a second histogram in the background. Remove member "light_histogram" from the GimpHistogramViewClass struct. * app/widgets/gimpcurveview.c: don't set "light_histogram". * app/tools/gimpcurvestool.c: set the background histogram instead. * app/widgets/gimphistogrameditor.[ch]: connect to "notify::frozen" of the drawable and show its histogram at the freezing point in the background. This way the original histogram is visible while we are doing color corrections. svn path=/trunk/; revision=24158
