If you're planning to use Starbase to gopen() an X11 window on the TSRX,
please be aware that Starbase graphics rendered using the "hp98731" 
(accelerated TSRX) driver will not be preserved by backing store.  Graphics
rendered using the "hp98730" (unaccelerated TSRX) driver will be preserved,
but only if the window depth is 8 bits or less.

This is discussed on pages 4-38 through 4-40 in the "Starbase Programming
with X11" manual.  As far as I know, this functionality has not changed 
for HP-UX 7.0.
