If the title of a frame matches REGEXP, then IMAGE.tiff is
selected as the image of the icon representing the frame when it's
miniaturized. If an element is t, then Emacs tries to select an icon
based on the filetype of the visited file.
The images have to be installed in a folder called English.lproj in the
Emacs folder. You have to restart Emacs after installing new icons.
Example: Install an icon Gnus.tiff and execute the following code
(setq ns-icon-type-alist
(append ns-icon-type-alist
'((\"^\\\\*\\\\(Group\\\\*$\\\\|Summary \\\\|Article\\\\*$\\\\)\"
. \"Gnus\"))))
When you miniaturize a Group, Summary or Article frame, Gnus.tiff will
be used as the image of the icon representing the frame. */);
