2001-01-23 Michael Natterer <mitch@gimp.org> * libgimp/Makefile.am * libgimp/gimp.h * libgimp/gimpadaptivesupersample.[ch] * libgimp/gimpbilinear.[ch]: new files cut out of LibGCK. * plug-ins/libgck/gck/gck.h * plug-ins/libgck/gck/gckcolor.c: removed the bilinear and supersample code. * app/apptypes.h * app/asupsample.[ch] * app/tools/blend.c: made the adaptive_supersample interface the same as in libgimp but don't use the libgimp function yet. The libgimp function takes total transparancy into account when weighting the 4 resulting RGBA values, the app function always weights them equally. Please have a look at the code. * plug-ins/Lighting/lighting_image.c * plug-ins/MapObject/mapobject_apply.c * plug-ins/MapObject/mapobject_image.[ch]: changed accordingly. * app/disp_callbacks.c: paranoia cleanups.
