It sounds like you need the capability of the HP-UX 3.1 server.  This
server supports 24 bit visuals on both the SRX and TSRX displays.  The
TSRX server allows a "combined" mode, wherein a client "sees" a choice
of two visuals - one which actually "resides" in the overlay planes and
one associated with the image planes.  The fact that the windows are in
two different sets of planes is hidden from the application and the
user.

On both the SRX and TSRX servers available for HP-UX 3.0 there is a
color "transparent" which allows an X client (with X running in the
overlay planes) to create a "hole" into the image planes.  You can have
a program which creates such a window and then uses Starbase to render
to the image planes.  It is up to the application to track the movement
of the window and set Starbase's P1 and P2 accordingly.  As of the HP-UX
3.1 release a Starbase program can render directly into an X window,
greatly simpifying the application.
