X window display sizes

[your name <your.name(at)gecm.com>]

There was an earlier question about finding the size of the display
screen. I am familiar with David's answer:-

	DEVICE, GET_SCREEN_SIZE = My_screen_size

However, I am running under OpenVMS, CDE, Motif with X-windows. In my
application, I create displays on a number of display devices using the
DISPLAY_NAME keyword to WIDGET_BASE.

Does anyone know how I can find the size of these (remote) displays?
Some of these displays are PCs with an X-window emulator, so the
resolution may be changed by the users without the knowledge of the
system.

Any help would be appreciated,

	Ian
