AdobeRGB is safe from this, with the exception of pure greens,which get
clipped just a hair at 255... larger spaces are clipped as I noted. That they
are not clipped or otherwise misconstrued with a Lab referenced transform is
something I have been told previously... but have not varified in practice. I
would note that the results in ColorThink look exactly as I described... a
big balloon blown up in a smaller box, with the corners clipped extensively.
But that may be a ColorThink imaging limitation.
