34 * The view major device is a placeholder device.  It serves
35 * simply to map the semantics of a graphics dipslay to
36 * the semantics of a character block device.  In other
37 * words the graphics system as currently built does not like to be
38 * refered to by open/close/ioctl.  This device serves as
39 * a interface to graphics.
