Michael Natterer d0a551bbf8 Cursor patch II: This is only the logic inside the cursor system and not
2000-06-09  Michael Natterer  <mitch@gimp.org>

	Cursor patch II:
	This is only the logic inside the cursor system and not yet used.

	* app/cursorutil.[ch]: [gimp]_change_win_cursor() take lots of
	parameters now and compose cursors from up to three cursor
	bitmaps/masks.

	* app/gdisplay.[ch]: As a test, create a hardcoded example cursor
	if "Cursor Mode" is set to "Tool Icon with Crosshair" in prefs.

	* app/curves.c
	* app/dialog_handler.c
	* app/scroll.c: changed the calls to the win_cursor function.

	* app/tools.[ch]: added a cursor and a toggle cursor to the ToolInfo
	structure of all tools.

	* app/toolsF.h: new ToolType TOOL_TYPE_NONE.

	* app/gimpdnd.c
	* app/interface.c: check for silly filenames in the file dnd
	callback. Closes #13733.

	* Makefile.am
	* cursors/bucket_fill_small.xbm
	* cursors/bucket_fill_small_mask.xbm
	* cursors/crop_small.xbm
	* cursors/crop_small_mask.xbm
	* cursors/crosshair_small.xbm
	* cursors/crosshair_small_mask.xbm
	* cursors/ellipse_select_small.xbm
	* cursors/ellipse_select_small_mask.xbm
	* cursors/eraser_small.xbm

	* cursors/free_select_small.xbm

	* cursors/rect_select_small.xbm
	* cursors/rect_select_small_mask.xbm
	* cursors/resize_small.xbm
	* cursors/resize_small_mask.xbm
	* cursors/zoom.xbm
	* cursors/zoom_mask.xbm
	* cursors/zoom_small.xbm
	* cursors/zoom_small_mask.xbm: new files extracted from Tigert's
	gimp-tool-cursors.xcf created at GimpCon.

	Tigert, I'll commit the xcf as soon as I've added empty layers
	with the names of the cursors that are missing.

	* cursors/mouse.xbm
	* cursors/mouse_mask.xbm: made it 32x32 to allow for cursor
	composition.
