>+ * USERPREF, U, user preferred is set from the xorg.conf Monitor
>+ * Option "PreferredMode" or from the Screen Display Modes statement.
>+ * This unique modeline is moved to the head of the list after sorting.

>+ * DRIVER, e, is set by the video driver, EDID or flat panel native.

>+ * USERDEF, z, a configured zoom mode Ctrl+Alt+Keypad-{Plus,Minus}.
>+ *
>+ * DEFAULT, d, a compiled-in default.
>+ *
>+ * PREFERRED, P, driver preferred is set by the video device driver,
>+ * e.g. the EDID detailed timing modeline.  This is a true sort
>+ * priority and multiple P modes form a sorted sublist at the list
>+ * head.
>+ *
>+ * BUILTIN, b, a hardware fixed CRTC mode.
