[evince] Adding a new key

[Alexandre Ziede <aziede tutanota com>]

Dear Evince developers,

I'd like to know if it's possible to add a new key called "window-maximized" to the schema "org.gnome.Evince.Default". The idea would be get better control to the behavior of the window of Evince when opening docs. It's worth to remember that such a key already exists for Gnome Documents and Gnome Books.

Kind regards,

Alexandre Ziede
