NSMenu* drawing efficency patch (try 1)

[Michael Hanni]

Howdy,

This small patch makes NSMenu* much more snappy on my PowerBook 3400c.  It
fixes a FIXME that has existed in the code for awhile and also saves the two
most used drawing selectors in the menu code.

ChangeLog:

2002-02-10  Michael Hanni <mhanni@sprintmail.com>

        * Source/NSMenuItemCell.m: cache drawTitle and drawKeyEquivalent  
        selectors as they were used most often in the menu code.
        * Source/NSMenuView.m ([-drawRect:]): make this more efficent,    
        only redraw cells that we clip.

Cheers!

Michael
