2001-10-22 Michael Natterer <mitch@gimp.org> General cleanup of the selection tools and their PDB wrappers: * app/core/Makefile.am * app/core/gimpimage-contiguous-region.[ch] * app/core/gimpimage-mask-select.[ch]: new files providing a clean, uniform API for the selection functionalities. Changed order of parameters to be consistent, removed code duplication. The region returned by the "by_color" function is not really contiguous but the API is so similar to "by_seed" and it's used in the same context so it's fair enough to put them together. Also, I'm not sure if the two is_pixel_sufficiently_different() I've optimized away were meant to do *exactly* the same. Added a comment there to remember the former difference. * app/core/gimpchannel.[ch] (gimp_channel_feather): removed the "output" channel parameter and made it optionally push an undo (like the other channel operations do). * app/core/gimpimage-mask.c: call gimp_channel_feather() with "push_undo == TRUE", removed some useless comments. * app/tools/gimpbycolorselecttool.[ch] * app/tools/gimpellipseselecttool.[ch] * app/tools/gimpfreeselecttool.[ch] * app/tools/gimpfuzzyselecttool.[ch] * app/tools/gimprectselecttool.[ch]: removed all the actual selection functionality and call the new gimp_image_mask_select_*() and gimp_image_contiguous_region_*() functions instead. * app/tools/gimpbezierselecttool.c * app/tools/gimpiscissorstool.c: use new function gimp_image_mask_select_channel() instead of doing the same manually. * app/tools/gimpbucketfilltool.c: find_contiguous_region() -> gimp_image_contiguous_region_by_seed(). * tools/pdbgen/Makefile.am * tools/pdbgen/groups.pl * tools/pdbgen/pdb/selection_tools.pdb: added new group "Selection Tools" which depends only on "core/" stuff (not on "tools/" any more, brrrr). * tools/pdbgen/pdb/text_tool.pdb: don't include "appenv.h" * tools/pdbgen/pdb/tools.pdb: removed the selection tools. * app/pdb/Makefile.am * app/pdb/selection_tools_cmds.c: new file. * app/pdb/internal_procs.c * app/pdb/text_tool_cmds.c * app/pdb/tools_cmds.c: regenerated. * libgimp/Makefile.am * libgimp/gimp_pdb.h * libgimp/gimpselectiontools_pdb.[ch]: new files. * libgimp/gimptools_pdb.[ch]: regenerated Misc cleanups: * app/app_procs.c: call splash_create() with "no_splash_image" as parameter. * app/display/gimpdisplay-render.c * app/display/gximage.c: don't include "appenv.h". * app/gui/gui.c: call session_restore() only if "restore_session" is TRUE. * app/gui/session.c: don't "if(restore_session)" here and don't include "appenv.h" * app/gui/splash.[ch]: added "gboolean show_image" parameter to splash_create(), don't include "appenv.h" * app/tools/gimppainttool.[ch]: added a "GimpGradient" parameter to gimp_paint_tool_get_color_from_gradient(). * app/tools/gimppaintbrushtool.c: pass the gradient. * app/tools/gimpselectiontool.c * app/tools/gimptransformtool.c * app/tools/tool_manager.c: s/GDisplay/GimpDisplay/. * app/widgets/gimpcontainergridview.[ch]: removed the "white_style" class variable and don't fiddle around with colors and styles... * themes/Default/gtkrc: ...do the same here with a simple rc style.
