2001-03-31 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/pixel_surround.[ch]: lowlevel stuff taken out of the transform tool. * app/tools/gimpscaletool.[ch]: minor cleanups, declare gimp_scale_tool_register() publically. * app/tools/gimptransformtool.[ch]: removed the PixelSurround stuff, hardcode tr_tool->interactive to TRUE, removed the no_draw() function, register the tool options, misc. other fixes and bad hacks that need to go away. (All this non-interactive stuff needs to be done outside the tool system. A "non-interactive tool" is just pure nonsense) * app/tools/gimptool.h: spacing. * app/tools/tool_manager.c: tool_manager_register_tool_options(): return after warning, don't simply continue and crash. * app/tools/tools.c: register the bezier select tool.
