2008-02-04 Michael Natterer <mitch@gimp.org> * app/base/gimphistogram.[ch]: add refcounting and replace free() API by ref() and unref(). * app/core/gimpdrawable-equalize.c * app/core/gimpdrawable-levels.c * app/widgets/gimphistogrameditor.c * tools/pdbgen/pdb/color.pdb: replace calls to gimp_histogram_free() by gimp_histogram_unref(). * app/pdb/color_cmds.c: regenerated. * app/widgets/gimphistogramview.c: reference the histograms so we don't need the widget's users to keep them around while the widget exists. * app/tools/gimpcurvestool.[ch]: remove the histogram from the tool struct and just create one locally to set it on the histogram view widget. Unrelated: * app/tools/gimplevelstool.[ch] * app/tools/gimpthresholdtool.[ch]: renamed "hist" members to "histogram" plus some cleanup. svn path=/trunk/; revision=24792
