<pre>I run my new patch which I will upload in a few seconds now through a
regression test and encountered 42 unexpected failures. But all of them uses a
Separation colorspace with name Black, and only the gray values are slightly
different. See i.e. bug-poppler25404.pdf:
It uses
[/Separation /Black /DeviceCMYK 12 0 R]
where the function converts it first to a CMYK value and then we use
GfxDeviceCMYKColorSpace::getRGB()
with a complex matrix multiplication to get it back to RGB
This of course results in different gray values than the new, much simpler gray
calculation!
So this is what I expected and can accept and is even closer to the spec.</pre>
