2001-12-02 Daniel Egger <degger@fhm.edu> * app/gimprc.c: Convert ugly comments into named structure fields. Much cleaner and less errorprone though may cause troubles on older compilers and then needs to be reverted. Please report! * app/base/base-types.h: Add FIXME reminder. * app/base/gimplut.c: Use CLAMP macro instead of if-cascade. * app/base/temp-buf.c: Remove duplicated calculations and simplify checks. * app/base/tile-manager.c: - (tile_manager_get_tile_num): Return success and take an additional pointer for the tilenumber. - Simplify logic in the rest of the file as a result. - Remove rotten debugging cruft. * app/core/gimpbrushgenerated.c: Fix two stylistic nits. * app/app_procs.c: Include <stdlib.h> for exit () prototype. * app/core/gimpdrawable-blend.c: Include <stdlib.h> for abs () prototype. * app/display/gimpdisplay.c: Include <string.h> for memcpy () prototype. * app/core/gimpimage-convert.c: (HIST_RGB): First parameter is not const. Fixes a gcc warning for a wrong return value. * libgimpwidgets/gimpunitmenu.c * app/core/gimpunit.c: Add suggested (by gcc 3.1 cvs) parentheses to group correct logic tests together. * app/paint-funcs/paint-funcs-generic.h: Fix my HAS_ALPHA macro to avoid gcc 3.1 cvs warning. * app/gimprc.h * pathP.h * base-config.h * app/base/boundary.h * app/base/gimplut.[ch] * app/base/pixel-region.h * app/base/pixel-surround.[ch] * app/base/temp-buf.[ch] * app/base/tile-manager-private.h * app/base/tile-manager.c * app/base/tile-private.h * app/base/tile.[ch] * app/core/gimp.h * app/core/gimpbrushgenerated.h * app/core/gimpbrushpipe.h * app/core/gimpchannel.[ch] * app/core/gimpcontainer.h * app/core/gimpcoreconfig.h * app/core/gimpdata.h * app/core/gimpdatafactory.[ch] * app/core/gimpdrawable-blend.c * app/core/gimpdrawable.[ch] * app/core/gimpimage.h * app/core/gimpimagefile.h * app/core/gimplayer.h * app/core/gimplayermask.h * app/core/gimpmoduleinfo.h * app/core/gimppalette.h * app/core/gimpundo.h * app/display/gimpdisplay.h * app/display/gimpdisplayshell-selection.h * app/display/gimpdisplayshell.h * app/gui/brush-select.h * app/gui/gradient-editor.h * app/gui/gradient-select.h * app/gui/info-dialog.h * app/gui/resize-dialog.h * app/tools/gimpbezierselecttool.h * app/tools/gimpcolorbalancetool.h * app/tools/gimpcolorpickertool.h * app/tools/gimpcurvestool.h * app/tools/gimpdodgeburntool.c * app/tools/gimpfreeselecttool.h * app/tools/gimpfuzzyselecttool.h * app/tools/gimphuesaturationtool.h * app/tools/gimpinktool-blob.h * app/tools/gimpinktool.h * app/tools/gimpiscissorstool.h * app/tools/gimpmagnifytool.h * app/tools/gimpmeasuretool.h * app/tools/gimppainttool.h * app/tools/gimppathtool.h * app/tools/gimprectselecttool.h * app/tools/gimpthresholdtool.h * app/tools/gimptool.h * app/tools/gimptransformtool.h * app/tools/path_toolP.h * app/widgets/gimpbrushfactoryview.h * app/widgets/gimpconstrainedhwrapbox.h * app/widgets/gimpcontainermenu.h * app/widgets/gimpcontainerview.h * app/widgets/gimpdialogfactory.h * app/widgets/gimpimagedock.h * app/widgets/gimplistitem.h * app/widgets/gimpmenuitem.h * app/widgets/gimpnavigationpreview.h * app/widgets/gimppreview.h: Unsignify lots of variables and parameters and use bitfields in structs where possible. First part of a huge cleanup all over the code...
