2001-02-24 Michael Natterer <mitch@gimp.org> * TODO.xml: updated. * app/appenums.h * app/apptypes.h: prefixed the cursor stuff with "Gimp", added the new stock tool cursor enum. Removed the old ToolType enum. * app/cursorutil.[ch] * app/gdisplay.[ch]: removed the old ToolType enum and prefixed the functions with "gimp_". Also stripped all "toggle cursor" stuff from the cursor code, so the new API is easier and not depending on the tool system. All existing tool cursors can be used via the new stock tool cursor enum, so no tool has to fiddle around with bitmap cursors. There will be an cursorutil function for registering stock tool cursor types on the fly. * app/disp_callbacks.c * app/scroll.[ch]: moved the display scrollbar callbacks from scroll.[ch] to disp_callbacks.c. Removed some crap from scroll.h * app/tools/tool.[ch]: removed the BitmapCursor pointers from the tool class struct and add cursor and toggle cursor IDs to the GimpTool struct. Work in progress. * app/dialog_handler.c * app/tools/bezier_select.c * app/tools/blend.c * app/tools/bucket_fill.c * app/tools/by_color_select.c * app/tools/clone.c * app/tools/color_picker.c * app/tools/convolve.c * app/tools/crop.c * app/tools/dodgeburn.c * app/tools/edit_selection.c * app/tools/ellipse_select.c * app/tools/flip_tool.c * app/tools/free_select.c * app/tools/fuzzy_select.c * app/tools/ink.c * app/tools/iscissors.c * app/tools/magnify.c * app/tools/measure.c * app/tools/move.c * app/tools/paint_core.[ch] * app/tools/perspective_tool.c * app/tools/rect_select.c * app/tools/rotate_tool.c * app/tools/scale_tool.c * app/tools/shear_tool.c * app/tools/text_tool.c * app/tools/transform_core.[ch]: changed accordingly. Did this "blind" for most tools because they don't compile. The changes are minimal, so there should be no conflicts.
