No, you can just draw on to the sub-region desired (if you need the  
background cleared for the sprite, you can draw a colored rectangle  
rather than use an entire glclear call). Make sense?

You can use the main sketch as this group buffer if you like as the  
above might suggest.

If you have a clear example where you are having issues with the  
suggested approach, we could point out any remaining issues.
