bug#16659: ns-use-native-fullscreen breaks fullscreen functionality on maverick secondary monitor when old spaces behaviour is selected, plus slow transition

[Luigi Rocca]

I am using the following emacs build, from http://emacsformacosx.com/
on an updated Mavericks installation: "GNU Emacs 24.3.50.1 
(x86_64-apple-darwin, NS apple-appkit-1038.36) of 2014-01-27 on 
bob.porkrind.org"

I'm disabling the native fullscreen functionality in my conf file (setq 
ns-use-native-fullscreen nil) and I have the OSX option "Displays have separate 
spaces" disabled.

While avoiding the native fullscreen does two very welcome things (the 
fullscreen window remains on the current space and the other monitor, if 
attached, is not greyed out) there are two problems:

1) Going fullscreen works only on the primary laptop monitor (I'm using a 
macbook pro) but not on the secondary monitor on the display port. When the 
emacs frame is on the secondary monitor, "M-x toggle-frame-fullscreen" has the 
following results:
- An animation of a small black rectangle goes out of the screen (headed to the 
lower right part of the screen - please note the secondary monitor is on the 
upper left wrt the primary one, don't know if this is related or not).
- A brief macosx error sound is played.
- The screen is now empty and emacs is nowhere to be seen, neither primary nor 
secondary monitor.
- The only way to get the emacs frame back is blindly calling 
toggle-frame-fullscreen again - the frame then returns to its previous position.

2) Even on the working primary monitor there is still a very slow scaling 
transition to fullscreen (and back). I find slow animations in Maverick to be 
annoying and nausea-inducing. Users that are disabling native fullscreen 
functionality are probably trying to disable the slow transition too (most 
other open source apps that give the user the option to disable the native 
fullscreen functionality, such as VLC and iterm2, do exactly this and avoid the 
slow animation entirely). It seems reasonable to either disable the animation 
when native fullscreen is disabled or add and additional option to disable it 
and/or control how fast it is (if I've missed one I'm sorry, please point it 
out to me).

I've tested one of the several unofficial osx emacs versions that were 
fullscreen-patched in the past 
(https://github.com/xajler/emacs24-macosx-lion-fullscreen) and it works as 
intended on both counts: it goes fullscreen on both monitors and without any 
animation whatsoever.

If there's anything I can do to help, test etc, please do tell me. I am 
confortable with building software from source and it is not a problem for me 
to checkout and build the latest sources if necessary.

Many many thanks for all the amazing work that the emacs developers have done 
in the past and are still doing on this amazing editor. Keep up the good work!
