2002-06-16 Michael Natterer <mitch@gimp.org> Fix for #85201: * app/tools/gimpfliptool.c: set the toggle_cursor correctly. * app/tools/gimptransformtool.c: if "use_grid" is FALSE, skip the cursor update stuff and chain up directly. Misc tool->control options fixes: * app/tools/gimppainttool.c: set "motion_mode" to GIMP_MOTION_MODE_EXACT. * app/tools/gimpairbrushtool.c * app/tools/gimpclonetool.c * app/tools/gimpconvolvetool.c * app/tools/gimpdodgeburntool.c * app/tools/gimperasertool.c * app/tools/gimppaintbrushtool.c * app/tools/gimpsmudgetool.c: don't touch "motion_mode" here. * app/tools/gimpimagemaptool.c * app/tools/gimptransformtool.c: set "scroll_lock" to TRUE and "preserve" to FALSE. * app/tools/gimpcurvestool.c * app/tools/gimphuesaturationtool.c * app/tools/gimplevelstool.c * app/tools/gimpfliptool.c * app/tools/gimpperspectivetool.c * app/tools/gimprotatetool.c * app/tools/gimpscaletool.c * app/tools/gimpsheartool.c: don't touch them here. * app/tools/gimphistogramtool.[ch]: derive it from GimpImageMapTool so it inherits it's control settings. * app/tools/gimpellipseselecttool.c: don't set "preserve" to TRUE. * app/tools/gimpmagnifytool.c * app/tools/gimpmovetool.c: code formating paranoia. * app/tools/gimptoolcontrol.c: fixed indentation.
