Confining cursors to CRTCs will come soon. can you add some information here as to why we need a new call and can't just update the existing ConstrainCursor hooks? and if we can't update the hooks, rename it to "ConstrainCursorToCRTC", since that's what it seems to do, guessing from the commit message.
