How do I find out what minor modes are in effect?

[Doug Lewan <dougl@shubertticketing.com>]

I'm writing a function that needs to change the major mode to do its stuff properly.
That can turn off minor modes too.
The obvious polite thing to do is turn them all back on when I'm done.

Resetting the major mode is easy:
(defun vertical-text (text)
  (let ((mode-to-restore major-mode)
    (picture-mode)
    ...
    (funcall mode-to-restore)))

How do I find out what minor modes are in effect?
And in what order they were invoked?
(They can stomp on each other and 
I'd rather not introduce bugs 
that are different from what the user already expects.

(Ultimately, I think this might be generally useful,
so a function like (save-mode) might emerge.)
