This device driver works by using the SunCore graphics routines
to draw on the workstation screen.
It works most naturally when using the Suntools window environment,
although it will work in a non-window environment.
When the driver is started, a new graphics window appears on
the screen.  This window can be repositioned and reshaped arbitrarily;
whenever the window is changed, the current plot will be redrawn to fit in
the new window.
.PP
When graphic input (`identify', `locator') is requested,
use the mouse to position the cursor and hit button 1 to make
a selection.  Buttons 2 or 3 terminate graphic input.
.PP
Since characters are vector-drawn, character sizes and rotations are arbitrary.
There are various line styles and colors.
.PP
A device must be specified before any graphics functions can be used.
