But this will hide real error messages too (such as X related errors).
And filtering wrappers have drawbacks and increase the risk of bugs
(to distinguish between what is really important to know and what
isn't).

Using "vince <file.pdf>" is often more practical.

Then these warnings should be given only for such users.
I suppose that there should be something in the environment
to be able to detect whether GNOME or XFCE or whatever desktop
envionment is supported is used.

OK.
