bug#35435: 26.1; Gnome magnifier not following cursor when typing in emacs

[Eric Danan]

Thanks for your reply. I don't have the knowledge (neither on the emacs 
code nor on X) to prepare such a patch, and I of course understand if no 
one else can do it, but I an otherwise happy to test things if that can 
help.

(Also cc'ing Alex Arnaud, which I forgot to do the first time.)
