-Pop up a dialog box.
-A dialog box description is a list.
-
-The first element of a dialog box must be a string, which is the title or
-question.
-
-The rest of the elements are descriptions of the dialog box's buttons.
-Each of these is a vector, the syntax of which is essentially the same as
-that of popup menu items. They may have any of the following forms:
-
- [ "name" callback <active-p> ]
- [ "name" callback <active-p> "suffix" ]
- [ "name" callback :<keyword> <value> :<keyword> <value> ... ]
-
-The name is the string to display on the button; it is filtered through the
-resource database, so it is possible for resources to override what string
-is actually displayed.
