[comp.windows.x] SaveUnders ??? What are they?

morreale@bierstadt.ucar.edu (Peter Morreale) (10/24/89)

In the twm man page, I noted that Tom was kind enough to 
include a twm variable entitled: NoSaveUnders

The question is,...  What are they?  In what circumstance would 
they be useful?

I looked in the O'Reilly version 3,... Can't seem to find anything 
about them....

Please note, I am only interested in this as a end-user, not a 
X programmer.

Thanx for any and all replies,
-PWM

Save Under is a feature similar to Backing Store that the server may
or may not provide.  If the server supports it and a client asks to
use it, this is what might happen: (how's that for disclaimers)  The
clients pops up a menu on which save unders have been requested,  the
server will save the image under the menu and replace the bits when
the menu comes down, thereby not generating expose events on underlying
windows.
