2008-01-23 Michael Natterer <mitch@gimp.org> * app/gegl/gimpoperationlevels.[ch] (gimp_operation_levels_map_input): new utility function which maps a single value. * app/tools/gimplevelstool.[ch] (levels_update_adjustments): use the new function to create the input arrays for gimp_color_bar_set_buffer(). Removed the Levels struct from the GimpLevelsTool struct and only use it in map() when needed. * app/base/levels.[ch]: remove obsolete API and struct members. svn path=/trunk/; revision=24682
