I think it was the use of the ‘visible’ method on NSToolbar, which it
appears I’ve made up, but which works on Cocoa. I’ve changed it to
look directly at the ‘isVisible’ instance variable.

I also noticed that it doesn’t like NSWindow:setStyleMask, so I’ve
changed that to directly update the relevant instance variable too.

I think some of the warnings are related to comparing an Objective C
object to NULL instead of nil, or vice versa. I can’t see any
difference between them here, and I don’t get any warnings from clang.

New patch attached.
