graphical <-
device: device*The device (normally picture, dialog or figure) on which the graphical
is displayed. A graphical can only be displayed on one device. The
graphical<->device
slot is used by graphicals to inform their device of changes, so the
device can perform the appropriate redraw operations. The following is
always true:
If the device of a graphical is not @nil, the graphical is
member of `Device <-graphicals` of this device and
visa-versa.
Normally, a graphical is assigned a device using device->display.
