Incremental fix on my Navigator work - switched out global to JGE vars actualWidth/Height to be real accessible members of the JRenderer instance, so that we can actually access what the real display width is from within the MTG project. This makes the fix for enchantment zone targetting work when the window is resized on Win32.
