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

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

I just noticed that Quesa on the Mac is doing its double buffer  
swapping without synchronizing with the vertical retrace of the  
monitor.  Adding the following code just before the end of  
gldrawcontext_mac_new() seems to correct the problem:

     // Tell OpenGL to sync with the vertical retrace of the monitor.
     {
         const GLint syncEveryFrame = 1;
         aglSetInteger( glContext, AGL_SWAP_INTERVAL, &syncEveryFrame );
     }

I didn't see any reference to this sort of thing in the archives so  
I'm not sure if it was omitted on purpose or if it was an oversight.   
If it was an oversight, I'd like see about getting it added to the  
actual CVS codebase.
