2002-05-03 Michael Natterer <mitch@gimp.org> * devel-docs/Makefile.am * devel-docs/includes.txt: new file documenting the core's include policy. * HACKING: mention it here. * libgimptool/gimptooltypes.h: removed GimpToolOptions here. * app/core/core-types.h: and added it here. This is a temp hack needed because GimpToolInfo needs to know the GimpToolOptions type. * libgimpproxy/gimpproxytypes.h: regenerated. * libgimptool/gimptoolmodule.h: don't include gimptooltypes.h here... * libgimptool/gimptoolmodule.c: ...but here. * app/config/gimpconfig-params.c: include "libgimpbase/gimpbase.h" entirely, not single files from it. * app/core/gimp.c * app/core/gimpcontext.c * app/core/gimpcoreconfig.c * app/core/gimpdatafactory.c * app/core/gimpdocuments.c * app/core/gimpdrawable-blend.c * app/core/gimpdrawable-bucket-fill.c * app/core/gimpdrawable-offset.c * app/core/gimpdrawable-transform.c * app/core/gimpdrawable.c * app/core/gimpedit.c * app/core/gimpimage-convert.c * app/core/gimpimage-crop.c * app/core/gimpimage-duplicate.c * app/core/gimpimage-guides.c * app/core/gimpimage-mask.c * app/core/gimpimage-merge.c * app/core/gimpimage-new.c * app/core/gimpimage-projection.c * app/core/gimpimage-qmask.c * app/core/gimpimage-resize.c * app/core/gimpimage-scale.c * app/core/gimpimage.c * app/core/gimpitem.c * app/core/gimpmodules.c * app/core/gimppaintinfo.c * app/core/gimpparasite.c * app/core/gimppreviewcache.c * app/core/gimptoolinfo.c * app/core/gimpunit.c: include "core-types.h" and no other types file. * app/display/gimpdisplay.c * app/display/gimpdisplayshell-callbacks.c * app/display/gimpdisplayshell.c: include "tools/tools-types.h" instead of "libgimptool/gimptooltypes.h", warn about inclusion on "gui/gui-types.h" * app/file/file-open.c * app/file/file-save.c: don't include "libgimptool/gimptooltypes.h". * app/gui/about-dialog.c * app/gui/brush-select.c * app/gui/brushes-commands.c * app/gui/color-select.c * app/gui/data-commands.c * app/gui/device-status-dialog.c * app/gui/dialogs.c * app/gui/gradients-commands.c * app/gui/help-commands.c * app/gui/info-window.c * app/gui/palettes-commands.c * app/gui/patterns-commands.c * app/gui/resize-dialog.c * app/gui/tips-dialog.c * app/gui/tool-options-dialog.c: include "gui-types.h" and no other types file. * app/paint/gimpairbrush.c * app/paint/gimpclone.c * app/paint/gimpconvolve.c * app/paint/gimpdodgeburn.c * app/paint/gimperaser.c * app/paint/gimppaintbrush.c * app/paint/gimppaintcore-stroke.c * app/paint/gimppaintcore.c * app/paint/gimppaintoptions.c * app/paint/gimppencil.c * app/paint/gimpsmudge.c * app/paint/paint.c: include "paint-types.h" and no other types file. * app/pdb/pdb-types.h: don't include "libgimptool/gimptooltypes.h". * app/plug-in/plug-in-progress.c: warn about inclusion of "display/display-types.h" * app/tools/tools-types.h: include "libgimptool/gimptooltypes.h". * app/tools/gimpairbrushtool.c * app/tools/gimpbezierselecttool.c * app/tools/gimpblendtool.c * app/tools/gimpbrightnesscontrasttool.c * app/tools/gimpbucketfilltool.c * app/tools/gimpbycolorselecttool.c * app/tools/gimpclonetool.c * app/tools/gimpcolorbalancetool.c * app/tools/gimpcolorpickertool.c * app/tools/gimpconvolvetool.c * app/tools/gimpcroptool.c * app/tools/gimpcurvestool.c * app/tools/gimpdodgeburntool.c * app/tools/gimpdrawtool.c * app/tools/gimpeditselectiontool.c * app/tools/gimpellipseselecttool.c * app/tools/gimperasertool.c * app/tools/gimpfliptool.c * app/tools/gimpfreeselecttool.c * app/tools/gimpfuzzyselecttool.c * app/tools/gimphistogramtool.c * app/tools/gimphuesaturationtool.c * app/tools/gimpinktool.c * app/tools/gimplevelstool.c * app/tools/gimpmagnifytool.c * app/tools/gimpmeasuretool.c * app/tools/gimpmovetool.c * app/tools/gimppaintbrushtool.c * app/tools/gimppainttool.c * app/tools/gimppathtool.c * app/tools/gimppenciltool.c * app/tools/gimpperspectivetool.c * app/tools/gimpposterizetool.c * app/tools/gimprectselecttool.c * app/tools/gimprotatetool.c * app/tools/gimpscaletool.c * app/tools/gimpselectiontool.c * app/tools/gimpsheartool.c * app/tools/gimpsmudgetool.c * app/tools/gimptexttool.c * app/tools/gimpthresholdtool.c * app/tools/gimptoolcontrol.c * app/tools/gimptoolcontrol.h * app/tools/gimptransformtool.c * app/tools/gimpvectortool.c * app/tools/tools.c: include "tools-types.h" and no other types file, warn about inclusion of "gui/gui-types.h". * app/widgets/gimpcolorpanel.c * app/widgets/gimptoolbox-color-area.c: warn about inclusion of "gui/gui-types.h". * app/xcf/xcf-load.c * app/xcf/xcf.c: don't include "libgimptool/gimptooltypes.h". Split tool-safe-mode up in two files, one including libgimpproxy, one libgimp. * plug-ins/tools/Makefile.am * plug-ins/tools/tool-safe-mode-plug-in.[ch]: new files including libgimp/ stuff only. * plug-ins/tools/tool-safe-mode.[ch]: include libgimpproxy/ and libgimptool/ but don't include libgimp/ because of conflicting declarations. Unrelated: * app/tools/gimpclonetool.c: create the clone core so we don't crash. * app/gui/file-open-dialog.c: changed the way we create previews so that only out-of-date previews are created on a click in the preview area. Unconditional creation can still be forced by <Ctrl>+click. Changed the tooltip to document this.
