NEWT/OSX Pointer Invisible Fix: 10.6.* responder declarations & test focus/isInside

On OS X 10.6.8 the lack of responder method declarations (mouseEntered, ..)
lead to ignore the impl. callbacks.

'isMouseInside' cannot rely on 'mouseExit'/'mouseEntered' when
setMouseInvisible() is being called, deduce it manually.

focusLost == mouseExit (OS X behavior), hence focusGained needs
to set mouse invisible/visible in case it's requested.
