* app/tools_cmds.c: new file, containes the PDB stuff for most of the tools * app/gimprc_cmds.c: new file, PDB interface stuff for gimprc access * app/Makefile.am: added tools_cmds.c and gimprc_cmds.c * app/airbrush.[ch] * app/blend.[ch] * app/bucket_fill.[ch] * app/by_color_select.[ch] * app/clone.[ch] * app/color_picker.[ch] * app/convolve.[ch] * app/crop.[ch] * app/ellipse_select.[ch] * app/eraser.[ch] * app/flip_tool.[ch] * app/free_select.[ch] * app/fuzzy_select.[ch] * app/gimprc.[ch] * app/paintbrush.[ch] * app/pencil.[ch] * app/perspective_tool.[ch] * app/rect_select.c app/rect_select.h * app/rotate_tool.[ch] * app/scale_tool.[ch] * app/shear_tool.[ch]: bye bye PDB stuff (exported necessary enums functions, vars, etc.) * app/internal_procs.c: use register_foo functions * app/blend.[ch]: GradientType enum case changed * app/bucket_fill.[ch]: s/FillMode/BucketFillMode/, made the enum more consistent * app/clone.[ch]: capitalized the CloneType enum * app/color_picker.[ch]: changed get_color to pick_color so we don't conflict with colormaps.c get_color * app/convolve.[ch]: capitalized the ConvolveType enum * app/paint_core.h: made a GradientPaintMode enum * app/transform_core.h: BoundingBox enum * app/scale_tool.c: use the generic bounding box enum for X1, Y1, etc. * app/shear_tool.[ch]: turned HORZ and VERT into a ShearType enum -Yosh
