Re: Quesa on the Mac not synchronizing with monitor's vertical retrace

[Mikey <im...@be...>]

The reason I added this code in the first place was to correct  
tearing that was occurring while rotating the camera.  However, in  
the event that it does adversely affect someone's use of Quesa,  
perhaps it can be added as a field in the TQ3MacDrawContextData  
structure with its default set to zero.  If someone overrides the  
default, then retrace synchronization could be enabled as I described.
