What does screenColorSpace do? It seems like it will usually be wrong, and we should be getting it from the page/view, not the screen (because there are multiple screens).

You could call screenColorSpace(this) maybe? The PDFPlugin's Widget will be tied to the correct screen, then 'screenColorSpace' can give you the right answer, tied to the display the PDF is being shown on.

I used the PDF frame's view in the latest patch.

Thanks for reviewing, all!

How does this update if the screen colorspace changes?

That is a good point ... The current patch does not handle this, I believe.
