The usual way to do this is to use a resource editor, e.g. ResEdit to
create a cursor resource, then import the resource using the resource
manager (high level versions of which are in the file
"ccl:library;resources.lisp"). You should create the cursor with
a DEF-LOAD-POINTERS form so that it will be reloaded in a saved
application (objects in the Mac Heap are not saved by SAVE-APPLICATION).
I sent out an example last week showing how to define a cursor
completely in Lisp, but I don't advise that method.
