Use -(NSGraphicsContext*)[NSWindow graphicsContext] to obtain the adequate
graphics context to draw to a window. This requires Mac OS 10.4.
The advantage is that it is possible for a secondary thread to call
Fl_Window::make_current() without needing to create an autorelease pool.
We save the native graphics state, and also the state with origin at top.
Fl_X::q_release_context() restores the graphics state twice to return to
the native state. This allows to use a single graphics context for a single
window and a single thread.
Under 10.3, we have to create a new NSGraphicsContext when Fl_Window::make_current()
is called directly, so that secondary threads cannot call Fl_Window::make_current() without
having created an autorelease pool.
