	* app/core/Makefile.am
	* app/core/core-enums.[ch]: build with gimp-mkenums, added core-enums.c
	to CVS, added descriptions for GimpPreviewSize.

	* app/display/Makefile.am
	* app/display/display-enums.[ch]: build with gimp-mkenums, added
	display-enums.c to CVS, added descriptions for GimpCursorMode.

	* app/gui/preferences-dialog.c: more GimpEnumMenus.
