[Bf-funboard] Deep compositing.

[David McSween]

I know it maybe the future of compositing but the files really can be
enormous.  A lightwave forum suggested that they were creating 1920x1080 hd
frames at 100mb per frame, compressed!
So this is a lot to unpack into memory when you're using multiple elements
in a shot. Sometimes it's easier to just use a 2 masked element. And the
work load for balancing color between elements and their depth components
is a further time sink.

Also stereography or shooting left and right eye images doesn't provide the
best depth separation,  it is very coarse and hasn't removed the need for
green screen in movie production.
