There is a built-in list of viewers the user can choose from. And this
list is not supposed to be changed by the user. Therefore it is
declared with `defvar'. (The user can add or overwrite viewers in a
separate, customizable variable which is defined with `defcustom'.)
The idea now is that the list of predefined viewers only contains
viewers for the chosen platform. Per default viewers available on
GNU/Linux would be offered but if a theme for MiKTeX on Windows were
enabled, only viewers available on Windows would be displayed.
