Actually, looking at the code I'm mistaken - the sleep/wakeup happens automatically. Look at _swrast_InvalidateState() - if it gets a certain number of statechanges without doing any drawing, it unhooks itself from state updates. The "wakeup" is handled automatically next time drawing occurs (_swrast_update_state). I don't know if this actually helps performance, it's more an experiment. You don't have to worry either way though. Keith ------------------------------------------------------------------------- Take Surveys. Earn Cash.
