gimp/app/cursorutil.c
Michael Natterer 17335326d5 updated. 
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.
