2006-09-12 Michael Natterer <mitch@gimp.org> Added new tool API for modifier key events while the tool is active and implement it in the rect select and crop tools. Fixes bug #316156 and bug #355302. * app/tools/gimptool.[ch]: added GimpTool::active_modifier_key() and public function gimp_tool_set_active_motifier_state(). Remember the active_state at button_press and reset it on button_release. Ignore releases of modifiers that were pressed at button_press (but only ignore them once). * app/tools/tool_manager.[ch]: added wrapper tool_manager_active_modifier_state_active(). * app/display/gimpdisplayshell-callbacks.c (gimp_display_shell_events): return FALSE for all modifiers even when mouse button 1 is pressed. (gimp_display_shell_canvas_tool_events): when bouse button 1 is pressed *and* the tool is active, dispatch the new active_modifier events to tools. * app/tools/gimpcroptool.c * app/tools/gimprectangleselecttool.c * app/tools/gimprectangletool.[ch]: implement active_modifier_key() instead of modifier_key().
