plgra: Switch to graphics screen 

DESCRIPTION:

	Sets an interactive device to graphics mode, used in conjunction with
	pltext to allow graphics and text to be interspersed.  On a device
	which supports separate text and graphics windows, this command causes
	control to be switched to the graphics window.	If already in graphics
	mode, this command is ignored.	It is also ignored on devices which
	only support a single window or use a different method for shifting
	focus.	See also pltext.
