2008-10-09 Michael Natterer <mitch@gimp.org> Add GEGL_CFLAGS and #includes as if gimpdrawable.h and gimpimage.h had a GEGL dependency (they will have in the next commit, but I wanted to keep the commit separate). * app/dialogs/Makefile.am * app/file/Makefile.am * app/gui/Makefile.am * app/menus/Makefile.am * app/paint/Makefile.am * app/plug-in/Makefile.am * app/text/Makefile.am * app/vectors/Makefile.am * app/widgets/Makefile.am * app/xcf/Makefile.am: add GEGL_CFLAGS. * app/actions/*.c * app/core/*.c * app/dialogs/*.c * app/display/*.c * app/file/*.c * app/gui/*.c * app/menus/*.c * app/paint/*.c * app/pdb/gimppdb-utils.c * app/pdb/gimpprocedure.c * app/plug-in/*.c * app/text/*.c * app/tools/*.c * app/vectors/*.c * app/widgets/*.c * app/xcf/*.c: add <gegl.h> or replace <glib-object.h> by <gegl.h> to all files which include a drawable subclass or gimpimage.h * tools/pdbgen/app.pl: include <gegl.h> instead of <glib-object.h> in all generated files. * app/pdb/*-cmds.c: regenerated. * data/images/gimp-splash.png: the goat is still sleeping.
