The following question is related to page 365 of the IRIS Performer
Programming Guide, the frequently asked question "How do I overlay graphics
on top of my IRIS Performer scene?" .
For steps 3 (save and clear the projection matrix) and 5 (save and clear the
modelling matrix) of the answer what are the specific Performer calls to do
this? Also for steps 7 and 9 (restoring the modelling and projection
matrices).
Is there an example of this anywhere in the Performer library?
