I just noticed that Apple is using fullscreen all the timer after all.
E.g. if I use "quick look" on any file in Finder it has a fullscreen
button. Same in itunes. In both cases it simply fades the whole screen
to black without ever changing modes. Also if I enable the thing that
moving to screen edges does various stuff it can draw to the whole
screen and not just a window.

Neither Adobe Flash Player nor those OSX apps are open source of course
so can't look how they do it but at least I'm sure now with it being
such a standard thing also in OSX there should be some example code for
it around somewhere.

But yes, I wouldn't be surprised if behind the scenes it requires
creating a new OpenGL context which means it will not be so easy to
implement :/
