I just tried it out with OSX, and it looks quite good.  I've toyed
with this idea in the past, but we didn't have the screenshots
until a week ago (thanks again James!), so it didn't seem so
valuable.

Also, it involves yet more reshuffling of Documentation/ files, to
move the shared itexi files into a common location.  In order to
stop doing 8-hour days on lilypond, I refuse to do this myself,
but I have all the plans drawn up.  We'll see which helper gets to
it first.  No estimate on when that'll happen, though.

Added as 939.
