Alist for specifying screen dimensions in millimeters.

The functions display-mm-height and display-mm-width consult this list before asking the system.

Each element has the form (DISPLAY . (WIDTH . HEIGHT)), e.g.
(":0.0" . (287 . 215)).

If display is t, it specifies dimensions for all graphical displays not explicitly specified.

This variable was added, or its default value changed, in Emacs 22.1.
