Fullscreen magic zoom for 5D2

[shayok]

I see on magiclantern-v2.3.NEXT.2013Apr20.zip that fullscreen magic zoom is available for the 600D but not on 5D2. This, at 1:1 magnification, is incredibly useful and practically does away with the need for focus peaking.

Ah well...

zebra.c
#ifndef CONFIG_CAN_REDIRECT_DISPLAY_BUFFER_EASILY // old cameras - simple zoom box
                .max = 2,
                .help = "Size of zoom box (small / medium / large).",
#else // new cameras can do fullscreen too
                .max = 3,
                .help = "Size of zoom box (small / medium / large / full screen).",
