In my opinion, Apple screwed up badly on this one.  To make it work, you need
to implement a custom search procedure.  If your window is active (you have
received an Activate Event, but have not received a deactivate event), You
need to install it immediately before you do your CopyBits, and you need to
remove it immediately after your CopyBits.  (If you do all this, you do not
need to worry about the client ID, because your CopyBits is the only possible
client.)
