RTFM.  In this case,  section 4.1.4 of the ICCCM is the FM to R.  Pages 519
to 521 of the Digital Press 2nd edition.

In fact,  what you want has nothing to do with being iconified.  You
want to know if the window is worth going to the expense of updating.
It isn't worth doing so if the window is in normal state but buried
under other windows so as to be invisible.  See the last paragraph of
section 4.1.4 about VisibilityNotify.
