Subject: [PATCH] Don't minimize by default when in fullscreen desktop mode.
 This fixes behavior with the new Mac OS X fullscreen space code, as well as
 improve behavior on Linux desktops. The default for normal fullscreen mode is
 still to minimize because we're likely doing a mode switch and don't want to
 stick around as a borderless window in the background.
