[comp.sources.wanted] Using backing store from Xt?

Ok, I've "RTFM"ed and "UTS,L"ed and I still don't see any mention of this:

It would be nice to make use of backing store every once in a while.
Especially with programs like xmh and xcalendar.  That way when parts
of them are obscured I wouldn't have to wait for the program to update them.
I've tried this stuff out with other simpler programs like xmille and it
works real well.  S...o

How can I tell programs like xmh to use backing store when creating all
of their widgits?  Furthermore, how could anyone even tell the Xt
library routines to use backing store when creating *any* widget?  I
would have expected something like "XtNbackingstore" but there isn't
anything like that which I can find.  What's the deal?
