* app/tools/gimptransformtool.c
* app/tools/gimptransformtool.h: Started work on the TransformCore.
Very incomplete. Needs a friendly visit from genmarshal.pl. Not yet
included in the build. Move along now, folks, there's nothing more to
see.
2001-02-28 Nathan Summers <rock@gimp.org>
* app/tools/crop.c
* app/tools/crop.h: Fixed a couple instances where the crop tool was
incorrectly inheriting from GimpTool instead of GimpDrawTool. The crop
tool still does not work completely correctly on my machine. It does
not show the lines and sometimes it includes garbage.
