[Coco] DW4.1 preview video

[Aaron Wolfe]

Here are some of the new tricks DW has learned in the past year.  With
any luck I'll get everything ready for public affliction by the
CoCoFEST.

If anyone has info about the NIB graphics format used on a lot of the
CFDM disks, I'd be interested to know some details.  Right now I've
got the coco video emulation itself working fairly well but I havent
found much info to help with figuring out some of the old image
formats so I can render them into memory as pixels.
