I don't really want to change it, and actually "full" is what we use internally 
and really was the normal term pre-exr. I think both "full" and "display" can 
be misleading at times.

It's strange when you ask for the full image and it's smaller than the non-full 
image. But at the same time, you often display the data window instead of the 
display window and this it hard to make clear as well.
