No; this usage should be safe.  If you're only making *library* calls using
the stack-allocated RaatPort, the only process that needs the data is
yours, so it can be MEMF_PRIVATE.  You only need MEMF_PUBLIC if passing
the RastPort to Intuition or some such.  But in this case, it's going to
be around for a while, so you probably allocate it anyway.
