When windows aren't full-screen, non-floating windows go in NSNormalWindowLevel
and floating ones go in NSFloatingWindowLevel, which is higher.  However, a
non-floating full-screen window will go into a level higher than either of
those.  The prior logic of the -adjustWindowLevels: method would keep the
floating windows at a window level at least that high.  They should actually
be in a strictly higher level.
