The string "Screen" is incorrectly translated to "Mask" in gtk-2-4 (and HEAD)
where it should instead be translated to "Bildskärm" or maybe "Skärm". I guess
this translation has crept in from The GIMP where it should indeed be "Mask" (a
layer merge mode or something like that).

Anyway, in GTK+ the string "Screen" is used in two places:
- In the Extended input devices configuration dialog, where it is one of the
options that controls how a device should work (disabled, work on the whole
screen or in a window). (po/sv.po)
- As the name for the "screen" property for a window. The long english property
description is "The screen where this window will be displayed".
(po-properties/sv.po)

In both cases I think it is quite obvious that the current translation is incorrect.

Tack på förhand!
