[SDL] OpenGL + Timing

[Jim Tink]

Hello all,
I'm new to SDL and I've been through a lot of the tutorials listed on  
the tutorial page at libsdl.org.  But I'm having issues figuring out  
when to handle rendering. Should I use a SDL_AddTimer to add a timer  
function or should I use the delay function and render every 30 or so  
ms?

Thanks for helping,
Jim Tink
