branch: scratch/ns/refactor
commit 27df712e77fe41e806d462b5e147622ac220583a
Author: Alan Third <alan@idiocy.org>
Commit: Alan Third <alan@idiocy.org>

    Change NS port resize detection
    
    * src/nsterm.m ([EmacsView windowDidResize:]): Remove function, it's
    not performing a useful function any more.
    ([EmacsView viewDidResize]):
    ([EmacsView resizeWithOldSuperviewSize:]): Replace viewDidResize with
    resizeWithOldSuperviewSize.
    ([EmacsView initFrameFromEmacs:]): Remove the view resize notification
    as we don't need it any more.
