Timing Benchmarks using Sun Phigs

[ze'ev peter]

Can someone suggest how to time graphics calls in Sun Phigs?  When I call
a time() function before I draw lines and call time() after the drawing
function is called, I get both times back before the lines are even drawn!
This is probably due to some notifier loop in Sun Phigs which sits on top
of sunwindows.

Does anyone know how to do some simple time benchmarking for drawing
graphics using Sun Phigs?

Thanks very much.
