2001-11-10 Michael Natterer <mitch@gimp.org> * app/display/gimpdisplay-marching-ants.h * app/display/gimpdisplay-selection.[ch]: removed... * app/display/gimpdisplayshell-marching-ants.h * app/display/gimpdisplayshell-selection.[ch]: ...new names. * app/display/gimpdisplay.[ch] * app/display/gimpdisplayshell.[ch]: moved the Selection stuff from GimpDisplay to GimpDisplayShell. Renamed all functions which will stay in GimpDisplay from gdisplay_foo() to gimp_display_foo(). Added gimp_display_get_ID(), cleaned up the idle renderer. * app/image_map.c * app/plug_in.c * app/display/Makefile.am * app/display/gimpdisplay-foreach.[ch] * app/display/gimpdisplay-handlers.c * app/display/gimpdisplayshell-callbacks.c * app/display/gimpdisplayshell-handlers.c * app/display/gimpdisplayshell-scroll.c * app/gui/gui.c * app/gui/view-commands.c * app/tools/gimpeditselectiontool.c * app/tools/gimpinktool.c * app/tools/gimpmovetool.c * app/tools/gimppainttool.c * tools/pdbgen/pdb.pl: changed accordingly, cleanup. * app/pdb/display_cmds.c: regenerated.
