3 * VIM - Vi IMproved by Bram Moolenaar
4 * MacVim GUI port by Bjorn Winckler
6 * Do ":help uganda" in Vim to read copying and usage conditions.
7 * Do ":help credits" in Vim to see a list of people who contributed.
8 * See README.txt for an overview of the Vim source code.
13 * A window without any decorations which covers an entire screen.
15 * When entering full-screen mode the window controller is set to control an
16 * instance of this class instead of an MMWindow. (This seems to work fine
17 * even though the Apple docs state that it is generally a better idea to
18 * create a separate window controller for each window.)
20 * Most of the full-screen logic is currently in this class although it might
21 * move to the window controller in the future.
