Minimize button does not work on Mac

[claucece]

Currently, the minimize button of main window does nothing on Mac. Maximize and close buttons seem to work fine.

As seen in commit 24e2a65, creating our own minimize button, still gives the same behavior. This can be related, then, with 'gtk_window_iconify' or it not recognizing a window manager.

Is this still an issue? Any idea what the appropriate fix is?

[claucece]

Yeah, it is still an issue. Well, looking at the window manager to see if it recognizes it.

This has been fixed in the last commit. The problem was that by setting the TitleBar, we turned off native client side decorations on OS X. That, combined with a bug in gdk-quartz that doesn't make it possible to minimize undecorated windows, was the cause for this problem. By not setting the title bar, we will use the native controls on Mac OS X.
