Re: [Update REQ 5329]: running geomview in single-buffer mode

["Stuart Levy" <slevy>]

You can use the "(snapshot CAMID IMAGEFILE)" command to 
induce geomview to dump just the contents of an SGI window.  It switches
to single-buffered mode before taking the snapshot, then switches back.
The snapshotting is done with /usr/sbin/scrsave, so it produces an SGI-format
image file.

Alternatively, you can make geomview switch a particular window into
single-buffered mode permanently by typing "vs" with the cursor in a
graphics window.

There's no single command to induce this to happen via the command language,
but you can simulate typing "vs" into a particular window with the following
GCL commands:

(winenter CAMID)        # Pretend the mouse just entered that window;
                        # not needed if you have only one graphics window
(rawevent  49 1 0 0 0)  # Key sequence "1vs" guarantees switching into
(rawevent 118 1 0 0 0)  # single-buffered mode.
(rawevent 115 1 0 0 0)  # "0vs" (48 ... 118 ... 115) switches to double.
