How to make certain theme default?

[Wassily Kondratev <wk@xxxxxxxxxxx>]

New clients have "default" appearance, even if some theme has been applied
globally. How to make certain theme default?

I tried:

(defvar xwem-theme-new
;; ...
)

[code]
(defun my-xwem-theme-setup ()
  (xwem-theme-apply xwem-theme-new)
  (setf xwem-theme-default xwem-theme-new)
  )
(add-hook 'xwem-after-init-hook 'my-xwem-theme-setup)
[/code],

bit it did no effect. Experiments with xwem-cl-create-hook also gave nothing.
