2002-01-30 Michael Natterer <mitch@gimp.org> * libgimpwidgets/gimpcolorarea.c: pass a GdkGC to gdk_draw_rgb_image(), fixed dither offsets. * app/core/gimpobject.[ch]: new virtual function gimp_object_get_memsize(). * app/base/temp-buf.[ch] * app/base/tile-manager.[ch]: added *_get_memsize() methods. * app/core/gimp.c * app/core/gimpbrush.c * app/core/gimpbrushpipe.c * app/core/gimpbuffer.c * app/core/gimpchannel.c * app/core/gimpcontainer.c * app/core/gimpcontext.c * app/core/gimpdata.c * app/core/gimpdatafactory.c * app/core/gimpdrawable.c * app/core/gimpgradient.c * app/core/gimpimage.c * app/core/gimplayer.c * app/core/gimplist.c * app/core/gimpmoduleinfo.c * app/core/gimppalette.c * app/core/gimpparasitelist.c * app/core/gimppattern.c * app/core/gimppreviewcache.[ch] * app/core/gimpundo.[ch] * app/core/gimpundostack.c * app/core/gimpviewable.c: added get_memsize() implementations. * app/widgets/gimppreview.c * app/core/gimpobject.[ch]: some #ifdef DEBUG_MEMSIZE code to test the new memsize stuff (middle click any preview to get it's viewable's memory footprint).
